Scope of tetragonal Manganese based Heusler alloys in context of magneto crystalline anisotropy

Author(s): Gagandeep Aulakh
Abstract: Heusler compounds are a wonderful class of materials having wide range of extraordinary multi-functionalities including halfmetallic ferrimagnets and ferromagnets, multi-ferroics, shape memory alloys, tunable topological insulators, energy technologies, and magnetocaloric and thermoelectric applications. The tunability of this class of materials is outstanding and nearly every functionality can be designed. Heusler compounds show high spin polarization in spintronic devices. Manganese-rich Heusler compounds attract much interest in the context of spin transfer torque, spin Hall effect, and rare earth free hard magnets. Most Mn2-Heusler compounds crystallize in the inverse structure and are characterized by antiparallel coupling of magnetic moments on Mn atoms; the ferrimagnetic order and the lack of inversion symmetry lead to the emergence of new properties such as non-collinear magnetism, topological Hall effect, and skyrmions. We focus our attention on magneto crystalline anisotropy that have high values for tetragonal Heusler compounds.
