Realization of Interlayer Ferromagnetic Interaction in MnSb2Te4 toward the Magnetic Weyl Semimetal State



Taito Murakami, Yusuke Nambu, Takashi Koretsune, Gu Xiangyu, Takafumi Yamamoto, Craig Brown, Hiroshi Kageyama


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.
