Abstract:
Manipulation of spin states via purely electrical means forms the most advanced research branch, i.e. “all-electric spintronics”, in the field of spintronics. It wins an overwhelming focus in both fields of basic research and practical applications. In this paper, we briefly review recent progress relating to the all-electric spintronics, including electric-field control of Rashba spin-orbit coupling, magnetic anisotropy, exchange bias, and ferromagnetism, etc. Special focus is given to interface/surface systems, including semiconductor (oxide) heterostructures, magnetic/nonmagnetic surfaces, semiconductor/metal interfaces, and other nanostructures, which can be good candidates for spintronic functional materials.
Biography:
Prof. Chungang Duan earned his Ph.D. degree in theoretical physics from Institute of Physics, Beijing, Chinese Academy of Sciences, China in 1998. Then he worked in University of Nebraska, USA from 1998 to 2007. In 2008, he joined Department of Electronic Engineering, East China Normal University as full professor. He is now the deputy director of key lab of polar materials and devices, MOE. He has published more than 70 papers in peer-reviewed journals, including Nano Lett.‚ Phys. Rev. Lett.‚ Adv. Mater., Adv. Func. Mater. , with more than 1800 SCI citations. His group is currently working on multiferroics and magnetoelectric materials.
