Hard magnetic properties of the novel compound

The novel nitride with monoclinic structure is synthesized by gas - solid reaction. Its hard magnetic properties have been investigated by ball milling and magnetic measurements. The intrinsic coercivity increases with decreasing average particle size d and, after reaching a maximum at , then decreases slowly. increases also with increasing magnetizing field. A value of has been attained. The magnetizing field for obtaining coercivity saturation is about 1.5 T. The hard magnetic properties of remanence and energy product for are achieved at 293 K.
