STRUCTURAL AND MAGNETIC-PROPERTIES OF RMO1.5FE10.5NX

A systematic study of the structural and magnetic properties of the RM o1.5Fe10.5Nx series, where R is Y, Ce, Pr, Nd, Sm, Gd, Th, Dy, Ho, or Er, has been carried out using x-ray diffraction, magnetic measurement s, and the Mossbauer effect. The 1-12 phase with Ce and Pr has been su ccessfully stabilized. PrMo1.5Fe10.5Nx possesses excellent intrinsic m agnetic proper-ties, favorable for permanent magnet applications. The 1-12 phase, RMo1.5Fe10.5Nx, was also stabilized. Compared to RMo2Fe10N x, this compound shows a higher Curie temperature and a larger saturat ion magnetization due to the lower Mo content.
