New research on an atomically-thin semiconductor demonstrates how a material’s magnetism can be controlled using small amounts of strain. Published in Nature Nanotechnology, this study provides key insights for applications ranging from new spintronic devices to faster hard drives. This research was conducted by graduate student Zhuoliang Ni and led by assistant professor Liang Wu in collaboration with Penn’s Charlie Kane and Eugene Mele, as well as researchers from the University of Tennessee, Knoxville, Texas A&M University, the University of Fribourg, and Oak Ridge National Laboratory.
