摘要

Electron paramagnetic resonance (EPR) spectra of MnIn2S4 single crystals were studied at different temperatures. The EPR lines were found to have a Lorentz shape. A strong increase in the width of the resonance line ΔΗ and a shift in the g-factor occur in the paramagnetic phase with a temperature decrease in the region of 60–6.8 K. This shift is proportional to the line width: ∆g(T) ~ ΔΗ(T). The relaxation time is ~10-10 s and increases with increasing temperature.
