Abstract
Magnetism in the newly synthesized topological magnet Sb2MnTe4 is examined. Magnetic susceptibility, specific heat, and neutron diffraction measurements reveal a ferrimagnetic transition below 25 K, in contradiction to previous theoretical calculations. Together with first principle calculations, we argue that the material can be a prime candidate for type-II Weyl semimetal with broken time-reversal symmetry. Measurements on the bulk system enable us to identify the roles of site-mixing among cations, which has been unaddressed in interpretation of results from thin films.Citation
