Abstract

The structural and magnetic properties of the compound Sm_1.2Ho_0.8Fe₁₇ and the nitride powders Sm_1.2Ho_0.8Fe₁₇N_2.4 prepared by high energy ball milling under various milling regimes are reported. Magnetic properties of the samples are investigated at 2–300 K in steady magnetic field up to 70 kOe and in pulsed magnetic field up to 600 kOe. The application of high magnetic field reveals the presence of the second-order transition in Sm_1.2Ho_0.8Fe₁₇N_2.4 at 500 kOe. Magnetic hysteresis properties study shows that ball milling enhances magnetic performance of Sm_1.2Ho_0.8Fe₁₇N_2.4 making it perspective for the magnets fabrication.
