Magneto-Optical Kerr Rotation in Antiferromagnetic Semiconductor MnTe Thin Films: Evidence for Collinear Order and Domain Imbalance

This research paper presents the first observation of magneto-optical Kerr rotation in a collinear antiferromagnet, MnTe, challenging the belief that this effect is exclusive to non-collinear antiferromagnets and suggesting its potential for applications requiring stable magneto-optical effects under external magnetic fields.
