Peter Andreas Grünberg (German:[ˈpeːtɐˈɡʁyːnbɛʁk]; 18 May 1939 – 7 April 2018[1][2][3]) was a Germanphysicist, andNobel Prize in Physicslaureate for his discovery withAlbert Fert ofgiant magnetoresistance which brought about a breakthrough ingigabytehard disk drives.[4]

Life and career

[edit]

Grünberg was born inPlzeň,Czechoslovakia, which at the time was known as Pilsen in the German-occupiedProtectorate of Bohemia and Moravia (now theCzech Republic) to theSudeten German[5] family of Anna and Feodor A. Grünberg.[6] They first lived inDýšina[7][8] to the east of Plzeň. Grünberg was aCatholic.[9]

After the war, the family was interned; the parents were brought to a camp. His father, aRussia-born engineer who since 1928 had worked for Škoda, died on 27 November 1945 in Czech imprisonment and is buried in a mass grave in Plzeň which is also inscribed withGrünberg Theodor † 27. November 1945.[10] His mother Anna (who died in 2002 aged 100)[11] had to work in agriculture and stayed with her parents in the Petermann[12] house in Untersekerschan[13] (Dolní Sekyřany), where her children (Peter's sister was born in 1937) were brought later. The remaining Grünberg family, like almost all Germans, wasexpelled from Czechoslovakia in 1946. Seven-year-old Peter came toLauterbach, Hesse where he attendedgymnasium.[14]

Grünberg received his intermediate diploma in 1962 from theJohann Wolfgang Goethe University inFrankfurt. He then attended theTechnische Universität Darmstadt, where he received his BSc diploma in physics in 1966 and his Ph.D. in 1969. While there, he met and married his wife, Helma Prauser, who became a schoolteacher.[15] From 1969 to 1972, he did postdoctoral work atCarleton University inOttawa, Canada.[16] He later joined the Institute for Solid State Physics atForschungszentrum Jülich,Jülich, Germany, where he became a leading researcher in the field of thin film and multilayer magnetism until his retirement in 2004.[14]

In 1984–1985 he served as visiting scientist atArgonne National Laboratories,Lemont,Illinois, USA. From 1984 to 1992 he hadHabilitation process and was a lecturer (Junior Professor), and since 1992 till 2004 a Tenured Professor (ausserplanmässiger Professor) at theUniversity of Cologne, Germany. He was also a visiting professor at theTohoku University atSendai-shi,Miyagi-ken, Japan from 1998 till 2004.

In 2007, Grünberg was awarded Honorary Doctorate from theRWTH Aachen University, Aachen, Germany, in 2008 Honorary Doctorate from theSaarland University, and fromGebze Institute of Technology, and in 2009 from theUniversity of Athens.[16]

Important work

[edit]

In 1986 he discovered the antiparallel exchange coupling betweenferromagnetic layers separated by a thin non-ferromagnetic layer, and in 1988 he discovered thegiant magnetoresistive effect (GMR).[17] GMR was simultaneously and independently discovered byAlbert Fert from theUniversité de Paris Sud. It has been used extensively in read heads of modernhard drives. Another application of the GMR effect is non-volatile,magnetic random access memory.

Apart from the Nobel Prize, work also has been rewarded with shared prizes in the APSInternational Prize for New Materials, the International Union of Pure and Applied Physics Magnetism Award, the Hewlett-Packard Europhysics Prize, theWolf Prize in Physics and the 2007Japan Prize. He won theGerman Future Prize for Technology and Innovation in 1998 and was namedEuropean Inventor of the Year[18] in the category "Universities and research institutions" by theEuropean Patent Office andEuropean Commission in 2006.
