The diameters of these particles were estimated from X-ray diffraction patterns as ranging from 2 to 6 nm. Magnetization measurements were performed for each obtained sample under a ±50 kOe field. Magnetic parameters, such as saturation magnetization (Ms), permeability (μ) and coercivity (Hc), were determined from M-H curves. The relationship between saturation magnetizations Ms and the Zn concentration was almost similar to that between the saturation magnetization and Ni-Zn ferrite bulk crystal, however, the absolute values of Ms of the nanoparticles were about 30 % smaller than those of bulk crystal. The decrease of Ms in the nanoparticle system might be attributed to the canting surface spins or ion distributions. is the abstract. You may use this Word document template to write your article.
