H-T phase diagram of antiferromagnetic topological insulator MnBi2Te4 under hydrostatic pressure to 2.5 GPa

ORAL

Abstract

MnBi2Te4 is a layered compound that is an intrinsic antiferromagnetic topological insulator. Metamagnetic transitions have been observed at 3.2 T and 7.8 T at ambient pressure. By compressing the unit cell with hydrostatic pressure and applying a magnetic field we can track these metamagnetic transitions and investigate the magnetic ordering. In this talk I will present transport data and temperature-field phase diagrams of MnBi2Te4 single crystals up to 2.7 GPa and 9 T.
