Abstract
Sintered magnets of Sm2Fe17Ny nitrides, with a density of 6.0–7.4 g/cm3, have been prepared by using an explosion technique. Both crystalline structure and the magnetic properties of Sm2Fe17Ny nitrides were retained in the process. The sintered magnet had a remanence Br=0.83 T, an intrinsic coercivity μ0iHc=0.57 T and an energy product (BH)max=88 kJ/m3. The temperature dependence of coercivity and remanence were also measured. The temperature coefficients α of remanence and β of coercivity are −0.076%/°C and −0.51%/°C, respectively.This publication has 15 references indexed in Scilit:
