Author(s): Gagandeep Aulakh
Abstract: Heusler compounds are an extraordinary class of materials having a wide range multi-functional properties including halfmetallic ferromagnets, antiferromagnetism, multi-ferroics, shape memory alloys, and tunable topological insulators, energy technologies, and magneto-caloric applications. Heusler compounds are a huge family of binary, ternary and quaternary compounds. The widespread tunability of the Heusler compounds through chemical substitutions and structural pattern make these compounds especially interesting. Here in this article we take a glimpse of major developments in the field of Heusler compounds in the historical perspective. In the recent period, a variety of properties derived from topology which includes: topological metals with Weyl and Dirac points; a range of non-collinear spin textures including the very recent observation of skyrmions at room temperature; and giant anomalous Hall effects in antiferromagnetic Heusler compounds with triangular magnetic structures were observed. An outline of these major developments are given in case of Heusler materials within the context of recent emerging trends in condensed matter physics.
