ملخص

We present a study of the magnetic and structural properties of 1% Ho:Gd0.99-xLux alloys. X-ray diffraction patterns for 1% Ho:Gd0.99-xLux (x = 0.01, 0.39, and 0.59) show a single hexagonal type phase structure and the lattice parameters are found to depend on the Lutetium concentration. Magnetic measurements were made at temperatures between 100 K and 850 K using a vibrating sample magnetometer with a maximum field of 13.5 kOe. All the samples under investigation show a ferromagnetic behavior up to Curie temperature. The Curie temperature (Tc) and the saturation magnetization (Ms) are found to decrease with increasing the Lutetium concentration. The saturation magnetization is found to increase with decreasing the temperature (T) for all samples. The magnetic moment of 1% Ho:Gd0.98Lu0.01 at 0 K was estimated, to be (7.05 ± 0.05) μB/f.u., by extrapolating the Ms versus T 3/2 to T = 0 K. The results clearly indicate the formation of solid solution alloys.
