Magnetic properties of (Sm,Zr)Fe5 alloys and their nitrides

Magnetic properties of (Sm,Zr)Fe5 alloys and their nitrides

In this study, magnetic properties of (Sm,Zr)Fe5 melt-spun ribbons and their nitrogenated specimens were examined. The as-annealed (Sm,Zr)Fe5 melt-spun ribbons showed a coercivity of around 1.3 kOe, but it was found that their nitrogenation increased the coercivity. A high coercivity of 11.4 kOe was...

A high coercivity of 11.4 kOe was achieved in the (Sm0.7Zr0.3)Fe5 melt-spun ribbon when nitrogenated at 713 K for 20 h. Microstructural studies revealed that the nitrogenated specimen consisted of fine grains with an average diameter of 20 nm. XRD studies revealed that the nitrogenated specimen contained a small amount of the α-Fe phase together with the (Sm,Zr)Fe5 phase.http://dx.doi.org/10.1063/9.0000060
