A discovery in 1988 has yielded not only the 2007 Nobel Prize in Physics, but a birthing of subsequent DOE research and patents now at OSTI. GMR, or Giant Magnetoresistance, is considered an early application in the growing field of nanotechnology. In 1988, Dr. Peter Grünberg of Forschungszentrum Jülich in Germany and Dr. Albert Fert of Université Paris-Sud in France each independently discovered GMR, a physical effect in which very weak changes in magnetism generate larger changes in electrical resistance (see Office of Science press release). Dr. Grünberg's research was based in part on his work at DOE’s Argonne National Laboratory. Since the GMR discovery, DOE has contributed many research papers on the topic that can be viewed at OSTI’s Science Showcase.
