N2 - The hole doped manganites of perovskite structures have attracted great interest in the scientific community because the rich of physical behavior. In this work, we report the influence of Ni-doping on structure and magnetic properties of La0.67Ba0.33Mn1-xNixO3 (x =0, 0.02, 0.04, and 0.06). Stoichiometric quantities of analytical-grade La2O3, BaCO3, MnCO3, and NiO precursors with a purity of greater than 99% were mixed and milled using a Planetary Ball Milling during 25 hours, then calcined at 800°C for 10 hours, compacted, and continued with the process of sintering temperature of 1200°C for 2 hours. Samples were characterized using XRD (X-Ray Diffraction) then refined by GSAS software. Refinement results showed that the samples with various x = 0 to x = 0.04 had a single phase with monoclinic crystal structure, while the sample with x = 0.06, had two phases with monoclinic and hexagonal structures. Magnetic properties of La0.67Ba0.33Mn1-xNixO3 materials were characterized by permagraph. Hysteresis loops of La0.67Ba0.33Mn1-xNixO3 materials showed typical properties of soft magnetic materials. The total magnetization was found to be decreased as the x value to be increased in the samples.
