Ni Ni, a UCLA associate professor of physics, and her research team reported the discovery of the first intrinsic ferromagnetic topological insulator. They also reported in Nature Communications their discovery of an intrinsic magnetic topological insulator early this year.
“We are quite excited about these two sequential discoveries, which provide new material systems to explore new topological phenomena, such as quantized anomalous Hall effect, quantized magnetoelectric effect, and Majorana fermions,” she said.
