个人简介
Andrew Kent is a Professor of Physics at New York University. He received his Ph.D. from Stanford University in 1988 and conducted post-doctoral research at the University of Geneva in Switzerland and the IBM T. J. Watson Research Center. His research interests are in the physics of magnetic nanostructures, nanomagnetic devices and magnetic information storage. He has conducted experimental studies of quantum tunneling of magnetization and coherence in arrays of nanometer scale magnets known as single molecule magnets. He has also studied spin-dependent transport and spin momentum transfer in thin film magnetic nanopillars. Kent has expertise in thin film growth and characterization, device nanofabrication and high frequency measurements including, ferromagnetic resonance, electron paramagnetic resonance and time-resolved studies of magnetization dynamics. In 2007 he founded Spin-Transfer Technologies, a startup company developing spin torque magnetic random access memory devices. Kent is a fellow of the American Physical Society (APS), has served as chair of APS topical group on magnetism and its applications (GMAG) and is an advisory board member of the Committee of Concerned Scientists. He is on the executive committee of the APS Division of Condensed Matter Physics (DCMP) and Program Co-Chair of the 58th Annual Magnetism and Magnetic Materials conference (MMM 2013). Kent accomplishments were recognized by an Honorary Doctorate from the University of Lorraine (“Docteur Honoris Causa” de l'Universite de Lorraine), in September 2013. He received the French Jean d'Alembert Research Fellowship in 2017.
