Temperature dependence of EPR spectra of LiNc crystals. (A) Typical EPR spectra of LiNc crystals obtained under vacuum at 20, 40, 60, 80 and 270 K are shown. Spectrum at room temperature is given in Fig. 5. The EPR instrumental settings were: microwave frequency, 9.7 GHz; microwave power, 0.5 mW; modulation amplitude, 0. 25 G; modulation frequency, 100 kHz; receiver time constant, 41 ms; acquisition time, 15 s (single scan). (B) Temperature dependence of linewidth of LiNc crystals under vacuum. The peak-to-peak linewidth of LiNc crystals decreases with increasing temperatures. The inset shows the same variation on heating the sample.
