Mark Stiles
Mark Stiles is a physicist in the Electron Physics Group in the Center for Nanoscale Science and Technology at the National Institute of Standards and Technology (NIST). Mark’s research at NIST has focused on the development of ab initio theoretical methods for predicting the properties of magnetic nanostructures. He is a Fellow of the American Physical Society and he has served as a Divisional Associate Editor for Physical Review Letters. He received a M.S./B.S. in Physics from Yale University, and M.S. and Ph.D. degrees in Physics from Cornell University. Following postdoctoral research at AT&T Bell Laboratories, he joined the research staff at NIST. He is also an Adjunct Professor in the Department of Physics and Astronomy at the Johns Hopkins University.
A new connection between electricity and magnetism
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. Read More »
