Localized spin-polaron states in ferromagnets

V. V. Dyakin, B. M. Letfulov


Abstract: Electron states in ferromagnetic crystals with a single paramagnetic impurity which differs from host atoms only by the electron potential are investigated. It is shown that such an impurity creates a localized spin-polaron state and splits off an one-particle band from the band of two-particle electron-magnon states. Corresponding criteria for such effects are pointed out.
