Robert (Bob) McMichael is a physicist in the Electron Physics Group in the Center for Nanoscale Science and Technology (CNST) at the National Institute of Standards and Technology (NIST). Bob’s research at NIST has touched on a broad spectrum of phenomena in magnetic thin films and nanomaterials, but remains centered on micromagnetics and magnetization dynamics in magnetic thin films. He received a B.S. in Engineering-Physics from Pacific Lutheran University, and M.S. and Ph.D. degrees in Physics from The Ohio State University. He came to NIST in 1990 on an NRC Postdoctoral Research Fellowship, served on the research staff of the Metallurgy Division in the Materials Science and Engineering Lab, and then joined the CNST in 2007.
A magnetic domain wall moving along a ferromagnetic wire can generate a voltage across the wire. This electromotive force, which is not the same as Faraday’s law of induction, is part of a growing family of interactions that are being discovered in the field of spintronics.
