Vivek Amin

Vivek Amin is a UMD Postdoctoral Researcher in the Alternative Computing Group in the Nanoscale Device Characterization Division of the Physical Measurement Laboratory (PML). He received a B.S. in Electrical Engineering from The University of Texas at Austin and a Ph.D. in Physics from Texas A&M University. His doctoral research focused on the theoretical development of a novel imaging technique that measures spin textures using a scanned magnetic probe, and on how spin-orbit coupling affects thermoelectric properties in magnetic tunnel junctions. Vivek is working with Mark Stiles researching current-induced magnetization switching, specifically attempting to create new models of spin orbit torque in heavy metal/ferromagnetic bilayers.
