Comparative Study on Ni-Zn Ferrites by One-step Synthesis and Conventional Two-step Synthesis

The magnetic hysteresis parameters like coercivity (H_c) and saturation magnetization (M_s), and dielectric parameters like dielectric constant (ε') and dielectric loss (ε" /ε') of Ni_(0.5)Zn_(0.5)Fe_2O_4 prepared by "one-step synthesis" and conventional two-step synthesis methods, respectively, were comparatively investigated. It was observed that the saturation magnetization, dielectric constant and dielectric loss for samples prepared by "one-step synthesis" method are lower than those of ferrite samples prepared by conventional synthesis method. However, the coercivity of the former is higher due to its smaller grain size. The low dielectric loss makes these samples especially attractive for use at high frequencies.
