Abstract

Single-phase nanostructured YFe_1-xNi_xO₃ (x = 0.1; 0.15; 0.2 and 0.25) perovskites were formed after annealing a mixture of precipitated hydroxides at 800 °C for 1 h. The results showed that at the amount of Ni substitution over 0.3, NiO and Y₂O₃ phases were formed in parallel with the YFeO₃ phase. Moreover, as the amount of Ni substitution increased in the range of 0.1–0.5, the crystal sizes increased from 20 ± 3 to 22 ± 3 nm, while unit cell volumes decreased from 223.8 to 223.6 Å³. The magnetic parameters (H_c, M_r, M_s) of the nanostructured Ni-doped YFeO₃ perovskites were quite higher than those of pure YFeO₃, as well as of YFeO₃ doped Ca or Co. As the amount of Ni substitution is in the range of 0.1–0.25, H_c decreased from 1332.6 to 887.9 Oe, while M_s increased from 0.67 to 1.18 emu/g and M_r increased from 1.8⋅10⁻¹ to 3.2⋅10⁻¹ emu/g.
