Abstract
We succeed in stabilizing the PrMo1.5Fe10.5 compounds and their nitrides with ThMn12‐type structure. The single phase was identified by using x‐ray diffraction technique and thermomagnetic measurements. In PrMo1.5Fe10.5Nx, the c‐axis is the easy magnetization direction from 0 K to Curie temperature. The anisotropy field is up to 147 KOe at 1.5 K and 110 KOe at room temperature. In combination with a high Curie temperature of 640 K and a large saturation magnetization of 141.70 emu/g, these intrinsic magnetic properties are favorable for permanent magnet applications. As a preliminary attempt, a coercive force of 3.0 and 10.0 KOe was obtained at 300 and 1.5 K, respectively, by using hydrogenation disproportionation and desorption (HDD) processing.Keywords
