Electron paramagnetic resonance (EPR) spectra of Mn 2+ impurity ion in Stoichiometric LiNbO 3 single crystal (SLN) was investigated with an X-band EPR spectrometer in the temperature range of 3 K~296 K. The intensity of EPR spectrum of Mn 2+ 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 Mn 2+ ion substitute for Nb 5+ ion instead of Li + ion. No changes for
