Dr. Binek is Associate Professor in the Department of Physics and Astronomy at the University of Nebraska-Lincoln since 2009. He received his PhD in Germany at the University of Duisburg in 1995 followed by a Habilitation in 2001 giving him the opportunity of numerous research experiences abroad including neutron diffraction in Grenoble, France and calorimetry at the RIKEN institute in Tokyo/Wako, Japan. Dr. Binek’s most noticeable awards are the 1996 award of the Duisburger Universitätsgesellschaft for his outstanding PhD thesis and the Sigma Xi outstanding young scientist award in 2007. Dr Binek pioneered the field of perpendicular exchange bias [1]. He and collaborators were the first to propose and realize voltage-controlled exchange bias utilizing the magnetoelectric effect of chromia [2,3,4]. In 2005, Dr. Binek published a groundbreaking article on magnetoelectronics [5]. In 2010, he worked with Dr. Dowben and Dr. Belashchenko demonstrating electric control of boundary magnetization in chromia [6]. In addition to electrically controlled magnetism and spintronics, Dr. Binek is interested in fundamental thermodynamics and statistical mechanics. He discovered the field-induced Griffiths phase [7], pioneered magnetic thin film heterostructures for magnetocaloric materials design [8], contributed to the field of nonextensive thermodynamics [9], and provided the hitherto only thermodynamic theory of the exchange bias training effect [10]. Dr. Binek is author of 84 publications in peer review journals, a 2003 STMP monograph on Ising-type antiferromagnets, book chapters on magnetoelectrics and multiferroics, and co-author of a textbook on fundamental thermal physics which will be published by Wiley in 2013.
