Abstract Topologically non-trivial electronic structure is a feature of many rare-earth half-Heusler alloys, which host atoms with high spin-orbit coupling bringing in the non-triviality. In this article, using the first-principles simulations, rare-

Abstract Half-Heusler compounds exhibit a remarkable variety of emergent properties such as heavy-fermion behaviour, unconventional superconductivity and magnetism. Several of these compounds have been predicted to host topologically non-trivial elec

CaMn7O12 is a magnetic multiferroic material, in which large ferroelectric polarization has reportedly been induced by magnetic ordering. In this work, we observe remarkable changes in the spontaneous ferroelectric polarization PS as well as the magn
