John Slonczewski
John Casimir Slonczewski (born July 26, 1929 in New York City , † May 31, 2019 in Katonah ) was an American solid-state physicist who carried out research for IBM .
Slonczewski graduated from Worcester Polytechnic Institute with a bachelor's degree in 1950 and received a PhD in physics from Rutgers University in 1955 . From 1955 he was at the Thomas J. Watson Research Center of IBM in Yorktown Heights in New York. He stayed there until his retirement in 2002 (except for sabbatical years at IBM's European research laboratory in Rueschlikon near Zurich in 1965/66, 1970/71 and 1987).
He dealt with the theory of graphite strips, the dynamic Jahn-Teller effect , structural phase transitions and in particular with magnetism: magnetic anisotropy, dynamics of bubble domains, magnetoresistance ( magnetic tunnel resistance , MTR), spin transfer moment between magnetic Films that are separated by tunnel barriers or metallic spacers (Magnetic Tunnel Junctions, MTJ), dynamics of magnetic vortices and exchange interaction between magnetic films. Some of this research was important for the development of magnetic storage and at times Slonczewski led research groups of theorists and experimenters at IBM.
Most recently he did research on thermally driven spin transfer.
In 2013 he received the Oliver E. Buckley Condensed Matter Prize for the prediction of the spin transfer moment and justification of the field of current-induced control over magnetic nanostructures (laudation). In 2012 he received the IEEE Magnetics Society Achievement Award and he received an IBM Outstanding Achievement Award. In 2006 he received the IUPAP Award and Neel Medal in Magnetism.
He was a fellow of the American Physical Society and a lifetime member of the Institute of Electrical and Electronics Engineers (IEEE).
