摘要: New procedures, employing the use of fractional distillation, have been developed for synthesis and purification GdN. Distilled undistilled GdN exhibit different magnetic behavior, both being sensitive to oxygen impurities. The zero field moment a virgin sample distilled is but with increasing exhibits features ferromagnetic behavior. For GdN, an increase in concentration from 0.8 5.8 at.% decreases paramagnetic Curie temperature 90 60 K. Undistilled having large nitrogen deficiency, shows
