摘要：

Electron paramagnetic resonance (EPR) spectra of Mn2+ impurity ion in Stoichiometric LiNbO3 single crystal (SLN) was investigated with an X-band EPR spectrometer in the temperature range of 3 K similar to 296 K. The intensity of EPR spectrum of Mn2+ ion was increased to 20 K and decreased again below 20 K as the temperature decreases. The zero-field splitting parameter D decreased as the temperature increases. It was suggested that Mn2+ ion substitute for Nb5+ ion instead of Li+ ion. No changes for hyperfine interaction of Mn2+ ion was obtained in the temperature range of 3 K similar to 296 K.
