Effects of the silica content and temperature on the magnetic properties of Ni0.5Zn0.5Fe2O4/SiO2nanocomposites have been studied by electron paramagnetic resonance (EPR) technique. The peak-to-peak linewidth (ΔHPP), g factor and spin number (NS), measured at room temperature, decreased with increasing SiO2content, while the spin-spin relaxation time (T2) increased. Furthermore, these parameters (ΔHPP, g factor, NSand T2) were measured as function of temperature. The ΔHPP, g factor and NSdecreased with increasing temperature whereas the T2increased. © 2004 Elsevier B.V. All rights reserved.
