报告题目：Angular momentum transport in Spintronics
报告人：Prof. Shufeng Zhang (张曙丰)
Electron spins and quasi-particle magnons are two types carriers that play a central role in propagating angular momentum information in spin-based electronics. I will start with describing fundamental differences between charge and spin/magnons current, followed by a discussion on various “spin batteries” that are used for spin current generation, manipulation and detection in magnetic and non-magnetic layered structure. The main focus of the talk is on the recent theoretical and experimental advances in finding novel phenomena associated with the spin-magnon current, in particular, how different spin current carriers mutually convert at interfaces in several classes of materials including antiferromagnets. I will present a number of predictions, some of them have been confirmed experimentally.
Professor Shufeng Zhang obtained B.S. from the University of Science and Technology of China in 1985 and Ph.D. from New York University in 1991. After he spent several years as a postdoc at the University of California-San Diego and at New York University, he held a faculty position at the University of Missouri (1998-2008). He moved to the University of Arizona in 2008 and has been a professor of Physics since. Professor Zhang is a condensed matter/materials theorist. His recent research interests are spin transport theory in magnetic systems. He is a fellow of American Physical Society (2005 class).
