High-field magnetostriction and magnetization in single crystals of g-wave altermagnet MnTe

ORAL

Abstract

A subset of materials with collinear and compensated magnetic moments can host interesting physical phenomena including the anomalous Hall effect and piezomagnetism owing to the spatial symmetries relating magnetic sublattices. MnTe is among the most investigated of these materials, often called altermagnets, because it has large spin-splitting between electronic states and becomes antiferromagnetically ordered just above room temperature. We report signatures of altermagnetism in MnTe single crystals utilizing magnetostriction and magnetization measurements up to 65T in pulsed magnets at the National High Magnetic Field Laboratory's Pulsed Field Facility.
