报告摘要：

Efficiently modulating spin configurations in magnets, especially by electrical means, is at the heart of spintronic devices. Novel magnets, such as 2D and topological magnets, couple topology, multiple degree of freedom, and magnetism, making them into promising materials for the high-efficiency spintronic devices previously impossible. I will give two examples of new paradigms for constructing efficient spintronic devices using novel magnets: 1) The efficient magnetism modulation in magnetic Weyl semimetal Co₃Sn₂S₂ nanoflakes with perpendicular magnetic anisotropy by direct current injection. 2) The high-order nonlinear magnetoelectric coupling (MEC) effect with a 2D stripy antiferromagnetic insulator CrOCl down to the 2D limit, verified by tunneling resistance measurement.

报告人简介：

Yu Ye is an associate professor in the School of Physics at Peking University. He received his Ph.D. degree in condensed matter physics from Peking University in 2012. Prior to joining PKU in July 2016, Yu was working as a postdoctoral researcher at the University of California, Berkeley. His group (http://faculty.pku.edu.cn/yeyu) currently is interested in light-matter interactions and electrical transport properties in condensed matter physics, with an emphasis on novel physical phenomena emerging in atomically-thin materials, van der Waals heterostructures and surfaces/interfaces by nanoscale device designs, low-T-high-B optical spectroscopy, and electrical transport measurements. Yu published more than 100 research papers and earned >7300 citations with an h-index of 40.
