Abstract
The electron spin resonance of a magnetic probe is considered in the interconfiguration-fluctuation host (ICF). The spin relaxation rate of a well-defined magnetic probe in the presence of the Coulomb interaction although satisfies the Korringa relation at low temperatures presents a minimum with a rise in temperature. The transition from the magnetic state to the non-magnetic state is also characterized by a minimum in the relaxation rate. The low temperature behavior of the relaxation rate with the distance between the magnetic probe and ICF ions is substantially lower than that of a pure metal.
