Abstract :
High performance injection molded Sm2Fe17N 3 anisotropic magnet is developed from the powder made by reduction and diffusion method. Remanence, coercivity and maximum energy product are 0.77 T, 0.78 T and 103 kT/m3, respectively in the density of 4.77 Mg/m3. The temperature coefficient of remanence is -0.07%/K. The initial irreversible flux loss is 5% at 100°C at a permanence of two
