Direct imaging of antiferromagnetic domains and anomalous layer-dependent mirror symmetry breaking in atomically thin MnPS${}_3$

Zhuoliang Ni, Huiqin Zhang, David Hopper +8

We have developed a sensitive cryogenic second-harmonic generation microscopy to study a van der Waals antiferromagnet MnPS${}_3$. We find that long-range Néel antiferromagnetic orde…
