Abstract

The influence of temperature on coercivity, H_c and saturation magnetization, M_s were investigated experimentally in Mn_0.5Zn_0.5Gd_0.02Fe_1.98O₄ ferrite nanoparticles (average size 35 nm). Isothermal magnetization curves M (H) were obtained in the field range from -5 kOe to +5 kOe at different temperatures after the zero field cooling (ZFC) process. The temperature dependence of the coercivity, H_c(T) deviated slightly from the classical Kneller's law. The temperature dependence of saturation magnetization, M_s(T) was found to have an excellent agreement with the Bloch's law. These results are discussed in terms of several factors such as the size and size distribution of the particles, inter-particle interactions and the surface spin.
