Dr. Peter Grünberg of Forschungszentrum Jülich in Germany has joined the growing list of Nobel Laureates associated with DOE. In 1988, Dr. Grünberg and Dr. Albert Fert of Université Paris-Sud in France each independently discovered Giant Magnetoresistance (GMR), a physical effect in which very weak changes in magnetism generate larger changes in electrical resistance. This is how information stored magnetically on a hard disk can be converted to electrical signals that the computer reads (see Office of Science press release).
The Royal Swedish Academy of Sciences awarded the 2007 Nobel Prize in Physics jointly to Dr. Grünberg and Dr. Fert for discovering “a totally new physical effect,” GMR (see featured documents), which revolutionized digital data storage and “can … be considered one of the first real applications of the promising field of nanotechnology.”
Dr. Grünberg's research as recognized in this year's Nobel Prize in Physics was based in part on his work at Argonne National Laboratory.
