Antiferromagnetic topological insulator with selectively gapped Dirac cones
A. Honma, D. Takane, S. Souma +14
Antiferromagnetic (AF) topological materials offer a fertile ground to explore a variety of quantum phenomena such as axion magnetoelectric dynamics and chiral Majorana fermions. T…

Observation of Giant Band Splitting in Altermagnetic MnTe
T. Osumi, S. Souma, T. Aoyama +6
We performed angle-resolved photoemission spectroscopy (ARPES) on hexagonal MnTe, a candidate for an altermagnet with a high critical temperature (TN=307 K). By utilizing photon-en…

Unusual surface states associated with the PT-symmetry breaking and antiferromagnetic band folding in NdSb
Asuka Honma, Daichi Takane, Seigo Souma +8
We have performed micro-focused angle-resolved photoemission spectroscopy on NdSb which exhibits the type-I antiferromagnetism below TN = 16 K. We succeeded in selectively observin…
