Abstract

Heusler compounds are a remarkable class of intermetallic materials with 1:1:1 (often called Half-Heusler) or 2:1:1 composition comprising more than 1500 members. New properties and potential fields of applications emerge constantly; the prediction of topological insulators is the most recent example. Surprisingly, the properties of many Heusler compounds can easily be predicted by the valence electron count or within a rigid band approach. The wide range of the multifunctional properties of Heusler compounds is reflected in extraordinary magnetooptical, magnetoelectronic, and magnetocaloric properties. Co2-Heusler compounds are predicted and proven half-metallic ferromagnets showing Slater-Pauling type behavior. The recently discovered Mn2-Heusler compounds are another class of half metallic Heusler compounds which even can be designed to be compensated ferrimagnets. Tetragonal Heusler compounds Mn2YZ as potential materials for STT applications can be easily designed by positioning the Fermi energy at the van Hove singularity in one of the spin channels. © 2013 Elsevier B.V.
