Giant intensity of magnetic dipole spin transitions in semimagnetic Van Vleck semiconductors
Rubo Yu. G. , Semenov Yu. G.
A resonant intensification of the effective dynamic g-factor occurs in the semimagnetic Van Vleck semiconductor A2 _ xFexB6 at frequencies close to the resonant frequencies of a spin-orbit multiplet of Fe2 + ions. This g-factor determines the intensity of magnetic dipole spin transitions of band electrons.
