摘要

研究了不同温度下MnIn2S4单晶的电子顺磁共振（EPR）谱。发现EPR线具有洛伦兹形状。在60 ~ 6.8 K的温度范围内，顺磁相的共振线宽度ΔΗ有明显的增加，g因子有明显的位移。这种位移与线宽成正比：∆g(T) ~ ΔΗ(T)。弛豫时间为~10 ~ 10s，随温度升高而延长。

Electron Paramagnetic Resonance of MnIn2S4 Single Crystals

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.
