Magnetic Properties of Sm-Fe-N Prepared by Melt-spun in Liquid N2 and High Gas Pressure Nitrogenation

摘要：

　　Sm-Fe-N was prepared by melt-spun Sm-Fe with liquid-N2-cooled copper wheel and nitrogen absorption under N2 gas pressures up to 25 MPa.The structure and magnetic properties of the Sm-Fe-N prepared under varied temperatures,N2 pressures and nitrogen absorption time have been investigated systematically.The liquid N2 melt-spun process improves the homogeneity of the samples while the high N2 pressure increases the efficiency of the nitrogenation process.The Sm-Fe-N decomposes under 25 MPa N2 at temperatures above 743 K.
