Interactions between conduction and magnetic electrons in europium chalcogenides

This paper is devoted to spin-orbit interactions between conduction and magnetic electrons. A model is proposed where the spin-orbit mechanism arises from intra-ionic spin-orbit coupling due to hybridization of conduction and magnetic electron wave functions. The physical consequences of spin-orbit interactions, e.g., the anomalous Hall effect, magnon amplification, and magnon drag, are discussed briefly.
