Abstract

The structural and magnetic properties of (PrxDy1-x)Fe10.5V1.5 compounds (x = 0 - 0.8) and their nitrides have been investigated by X-ray diffraction and magnetic measurements. It is found that single-phase V-stabilized (PrxDy1-x)Fe10.5V1.5 compounds can be formed in the Pr content range x = 0-0.8. The substitution of Dy for Pr in the compounds results in the decrease in the lattice parameters and saturation magnetization. The easy magnetization direction at room temperature turns from easy c-axis for x = 0-0.3 to easy plane for x = 0.4-0.8, while the Curie temperatures remain almost unaffected by the substitution of Dy, with TC values of about 590 K. Upon nitrogenation, the Curie temperature is increased to around 820 K, and the saturation magnetization increases by approximately 20%, while the easy magnetization direction lies along c-axis in the temperature range 0 K to TC. At low Dy contents, the (PrxDy1-x)Fe10.5V1.5Ny compounds have excellent intrinsic magnetic properties favourable for permanent magnet applications.
