Peter Grünberg (May 18, 1939) is a German physicist, and Nobel Prize in Physics laureate for his coincidental discovery with Albert Fert of giant magnetoresistance which brought about a breakthrough in gigabyte hard disk drives.[1]
Biography
Grünberg was born in Pilsen, Bohemia, which at the time was in the Nazi-occupied Protectorate of Bohemia and Moravia (now the Czech Republic) to the family of Fjodor Grinberg. His father changed his name from Grinberg to Grünberg in 1941. Like the rest of the German-speaking majority of Pilsen he had been expelled with the rest of his family by the Czech government by means of the Beneš decrees after World War II and came to Lauterbach, Hesse together with his mother and sister, where he attended gymnasium.[2]
Grünberg received his intermediate diploma in 1962 from the Johann Wolfgang Goethe University. He then attended the Darmstadt University of Technology in Germany, where he received his diploma in physics in 1966 and his Ph.D. in 1969. From 1969-1972, he did postdoctoral work at Carleton University in Ottawa, Canada. He later joined the Institute for Solid State Physics at the Jülich Research Centre, where he became a leading researcher in the field of thin film and multilayer magnetism until his retirement in 2004.[2]
Important work
In 1986 he discovered the antiparallel exchange coupling between ferromagnetic layers separated by a thin non-ferromagnetic layer, and in 1988 he discovered the Giant magnetoresistive effect (GMR).[3] GMR was simultaneously and independently discovered by Albert Fert from the Université de Paris Sud. It has been used extensively in read heads of modern hard drives. Another application of the GMR effect is non-volatile, magnetic random access memory.
Apart from the Nobel Prize, Grünberg's work also has been rewarded with shared prizes in the APS International Prize for New Materials, the International Union of Pure and Applied Physics Magnetism Award, the Hewlett-Packard Europhysics Prize, the Wolf Prize in Physics in and the 2007 Japan Prize. He won the German Future Prize for Technology and Innovation in 1998 and was named European Inventor of the Year[4] in the category "Universities and research institutions" by the European Patent Office and European Commission in 2006.
