Fig. 3: The crystalline structure and magnetic moment of Heusler compounds.
From: Emerging ferromagnetic materials for electrical spin injection: towards semiconductor spintronics
Schematic structures of (a) half Heusler (XYZ) and (b) quaternary full Heusler (XX’YZ) compounds. c The magnetic moment per formula unit of Co2-based Heusler compounds is in direct proportion to the number of valence electrons. This relationship follows the Slater-Pauling curve as illustrated in d. The values of 3 d transition metals and their alloys are provided for contrast.
