Abstract

The authors investigate the electron paramagnetic resonance (EPR) linewidth and amplitude of the Fe³⁺ ions in semimetallic HgSe:Fe. An effective spin relaxation mechanism caused by RKKY coupling between Fe³⁺ and Fe²⁺ ions is proposed to explain the experimental data. They conclude that the strongly nonuniform relaxation rate originating from the nonuniformity of the local environment of Fe³⁺, leads to a decrease of the EPR amplitude as observed in experiment.
