Magnetism in MnBi<sub>2</sub>Te<sub>4</sub> and related compounds
ORAL
Abstract
MnBi2Te4 has been extensively investigated recently as the first intrinsic antiferromagnetic topological insulator. This compound also shows a strong correlation between structural, magnetic, and transport properties. In this talk, I will present our work on how the stacking of septuple (MnBi2Te4) and quintuple (Bi2Te3) layers, chemical doping, high pressure, and antisite defects affect the magnetic properties. I will also discuss how these results can guide us fine-tuning the magnetism for desired topological phenomena.
