Peter Green Berger
German scientist Peter Green Berger was born May 18, 1939. From 1959 to 1963, John Green Berger in Frankfurt - Goethe University studying physics, intermediate diploma in 1962, received his PhD in 1969 in Darmstadt Technical University - Wolfgang.
1988 years, Green Berger study and found that giant magnetoresistance effect You Lixi Research Center; in 1992 was appointed Adjunct Professor, University of Cologne; after 32 years in 2004 to work in the Center for Retirement Research, but He continues to work.
the world-famous physicist, 2007 Nobel Laureate in Physics, Nanjing University of Posts and Telecommunications to introduce high-level personnel Peter Green Berger (Peter Grünberg) Professor illness is invalid, in 2018 4 May 7 in Germany, died at 79 years old.
academic
Green Berger winning quite good in academic areas, including in 1994, awarded by the American Physical Society International Prize for New Materials (with Albert Fert, Pa Kelin jointly awarded); 1998 awarded by the German President German future Prize; in 2007 won the Wolf Foundation Prize for Physics Prize (jointly awarded to Albert Fert)
discovery of giant magnetoresistance
and Phil Green Berger main contribution in the field of giant magnetoresistance. 1988, Phil Green Berger and each independently discovered giant magnetoresistance (GMR) effect (a phenomenon in effect when the external magnetic field, there is a huge change in resistivity than the magnetic material without external magnetic field). The discovery of billions of computer users to store large amounts of data on the hard drive, but also the process of downsizing in recent years, hard disk can be achieved, according to this effect the development of small high-capacity computer hard disk has been widely used. In the GMR system, minor changes in the magnetic force will have an enormous resistance, which in turn caused the differences changes the read head, 0 and 1 so as to identify when scanning the hard disk, in order to achieve data storage. With the development of technology, the read head can identify smaller and smaller, more and more weak magnetic area, this sensitivity means that the information can be stored more densely on the hard disk. In 1997 the technology for the first time put into practical use soon become a standard technology, today's most cutting-edge technology to read nothing but the further development of GMR technology.
role
GMR discovery also led to the first application of nanotechnology. According to the Royal Swedish Academy of Sciences said that the application of the giant magnetoresistance phenomenon is a revolutionary hard disk data recovery techniques, and in the development of a number of magnetic sensors and a new generator also played an important role. The technology for tiny devices, it can also be considered to be one of the first applications of nanotechnology. "Without this phenomenon, MP3 and iPod industry is impossible." The Royal Swedish Academy of Sciences said in an evaluation of this achievement, the Nobel Prize in Physics major reward "hard disk technology for reading the data." This technology is considered to be "one of the first practical application of the future of the vast field of nanotechnology."
Edit "physical world," the British magazine Physics Martin Duran, said: "This shows that physics is not just to understand natural phenomena, but also effectively related to people's daily necessities."
experience
Albert Fert aged 69, was born in the historic city of Carcassonne in southern France, in 1970 received his PhD from the University of South Paris, since 1976, taught at the University of South Paris . Since 1995 scientific director of the French Institute CNRS physics.
Peter Green Berger, now 68 years old, born in Germany Plzen, 1969 PhD Technical University of Darmstadt in Germany, since 1972 under the Forschungszentrum Jülich in Germany a research institute to teach.
will
work to Shandong University2011 Nian 11 22 morning, held in 2011 Fifteenth Shandong University president's office, meeting validated by the Nobel Prize in Physics obtained personnel who Professor Peter Green Berger introduction program.
"is now in the Alexander." 23, Shandong University in the Director of Personnel told reporters. To the Commissioner said Peter Green, Alexander Berger is the introduction of the first Nobel Prize winner, Professor Samuel Ting and different to Alexander many times, "said Professor Samuel Ting is because there are feelings of Alexander, his relationship with Alexander is cooperation, Alexander is the need to pay Peter Green Berger reward. "
to Commissioner said Peter Green Berger has promised to carry out research in two to three months each year Alexander, he Alexander's main job is to build a multi-field regulation physics and devices laboratory at the School of Physics, in order to promote academic development. "His vision is relatively high, in order to introduce some vision of his staff, then form a team, Alexander is likely to achieve world-class in the direction of his research." The Registrar explained that Alexander also value the Peter Green Berger disciplinary influence, he hopes to attract more teachers to Alexander, "because this person, so more teachers willing to Alexander."
reporter access to Shandong University official website was informed that Peter Grünberg Dole and Alexander quite closely, he visited Alexander last July 30 to August 8, and revealed the future have the opportunity to revisit the idea of Shandong University.

Winner reflections
French scientist Albert Fert and German scientist Peter Green Bay Siegel
The Royal Swedish Academy of Sciences announced Monday, the French scientist Albert Fert and German scientist Peter Green Berger discovery of "giant magnetoresistance effect" shared the 2007 Nobel Prize in Physics. After winning two scientists that the media were issued a brief acceptance speech.
Albert Fert in a telephone interview, said:. "I'm flattered, very moved, I was able to share this award with Peter Green Berger and excited that we just talked to us always a good exchange of our findings. "
the two scientists found that making small hard drive capacity has been widely used. Phil said, "Our findings can see the power generated is great!"
Peter Green Berger in an interview with Swedish radio, said: "I was told that if there is from Stockholm to the phone, it can only be a Nobel Prize (notice). "he said," is there a crowd of people standing outside my door, "he intends to follow them," a glass of champagne. "
Honors and Awards
Peter Green Berger
In 1998 the German Federal President Roman Herzog awarded to Grinberg German Future Prize (Deutscher Zukunftspreis), in recognition of his discovery of the giant magnetoresistance effect.
In 2002 he was "Grinberg principle" to get an honorary doctorate at the University of Bochum.
In 2003 received the highest award in science and research awarded the Sudetenland, "Gerstner Knight" (Ritter-von-Gerstner-Medaille).
In 2006 was named head of department of the European Commission and the European Patent Office, universities and research institutions for the "European Year inventor."
2007 was awarded the German Physical Society "Stern - Gerlach Medal" (Stern-Gerlach-Medaille), as well as Israel's parliament issued a "Wolf Prize."
April 19, 2007, Grinberg National Theater in Tokyo, Japan, and the University of Paris XI Albert Fert accepted with "Japan Prize" in recognition of the two solid physicists discovered giant magnetoresistance effect, Scholarship of up to 350,000 euros.
9 October 2007 the Nobel Foundation announced that Albert Fert and Grünberg each independently discovered because of the giant magnetoresistance effect, shared the Nobel Prize in Physics for 2007, and 2007 December 10 awards in Stockholm.
People influence
French scientist Albert Fert
Grinberg is one of the earliest scientists magnetic effect of "thin", which is the door research branch called spintronics using the spin properties of electrons, the future will achieve a new type of miniature circuit.
1986 years Grinberg discovered iron - chromium - antiferromagnetic coupling within the iron layer.
From 1987 to 1988, Grinberg almost Aier Bo Phil also found that the giant magnetoresistive effect, so that increases the storage capacity of the hard drive in the late 1990s, and now almost all of the hard disk read and write the head read function is based on the giant magnetoresistive effect.
You Lixi Research Center in 1988, such filing a patent, "a magnetic field sensor implemented with a thin layer of ferromagnetic" licensing of this patent, to bring tens of millions You Lixi Research Center euro benefit.
