Electronic structure, magnetic and optical properties of image Heusler alloy Original Research Article

The article describes the electronic structure, magnetic and optical properties of bulk image Heusler alloy. It is shown that unlike most stoichiometric full-Heusler alloys, the bulk image crystallizes into the face-centered cubic (fcc) lattice of image image-type ordering, with a Curie temperature of 800 K, with small admixture of B2-phase. The magnetic and optical properties of image Heusler alloy are discussed in terms of energy band calculations for ordered fcc and image-type structure. According to the results of our first-principles calculations, the full electron energy of ferromagnetic metallic fcc phase image is lower by about 0.06 meV (0.69 K) than that of ferrimagnetic half-metallic phase with image structure image.
