Piezomagnetic properties in altermagnetic MnTe
Takuya Aoyama, Kenya Ohgushi
Abstract
This study presents experimental results of the piezomagnetic effect in MnTe, one of the candidate materials for altermagnets. The piezomagnetic effect is a cross-correlation between magnetization and stress that is allowed in materials with broken time-reversal symmetry. The authors observed magnetization proportional to the stress below the antiferromagnetic transition temperature, indicating that MnTe has characteristics of altermagnets. They also demonstrated that the altermagnetic domains can be controlled via the piezomagnetic effect.
