Coexistence of Anomalous Hall Effect and Weak Net Magnetization in Collinear Antiferromagnet MnTe

Understand

Anomalous Hall effect (AHE) plays important role in the rapidly developing field of antiferromagnetic spintronics.

• It has been recently discussed that it can be a feature of not only uncompensated magnetic systems but also in altermagnetic materials.
• Hexagonal MnTe belongs to this appealing group of compounds exhibiting AHE and is commonly perceived as magnetically compensated.
• Here, we demonstrate that bulk form of MnTe exhibits small but detectable magnetic moment correlating with hysteretic behaviour of the AHE.
