Prospect for tunneling anisotropic magneto-resistance in ferrimagnets: spin-orbit coupling effects in Mn3Ge and Mn3Ga

Original language description

Magnetic anisotropic phenomena in Mn3Ge and Mn3Ga ferrimagnets are studied by first-principles density functional theory calculations. We find a large positive magnetic anisotropy energy, associated with the Mn-atoms in the 4d-crystallographic positions. Sizable anisotropy in the density of states is found in the vicinity of the Fermi energy, and suggests the promising possibility for the generation of a sizable tunneling anisotropic magneto-resistance effect (TAMR). The use of the ferrimagnetic materials for TAMR magnetic tunneling junctions is discussed as a prospective alternative for ferromagnetic and antiferromagnetic materials.
