Abstract
Magnetic properties of Sm2Fe17Nx and SmFe5Ny with different nitrogen contents are studied. It was found that the magnetocrystalline anisotropy for both Sm 2Fe17Nx and SmFe5Ny alloys changes from easy plane to easy axis at x >0.13 and y >0.07. The 1:5, 1:3, and α-Fe phases coexist in homogenized SmFe5 alloy. Nitrogenation reduces the 1:3 and α-Fe phases, and stabilizes the 1:5 phase in SmFe5Ny alloys. The transition in magnetocrystalline anisotropy from easy plane to easy axis for Sm2 Fe17Nx and SmFe5Ny alloys is gradual and dependent on nitrogen content
