The Exchange Parameters in Lanthanum Manganites

The spin-wave spectrum in the metallic ferromagnetic lantha-num cubic manganites was investigated. The interactions with four coordination spheres (32 neighbors) were taken into ac-count. The Heisenberg superexchange between all manganese ions as well as double exchange between the manganese ions wi...
