Abstract
Ni0.25Cu0.2Zn0.55SmxFe2−xO4 ferrite with x=0.00, 0.025, 0.05 and 0.075 compositions were synthesized through the nitrate–citrate auto-combustion method. These powders were calcined, compacted and sintered at 900 °C for 4 h. Effect of Sm substitution on phase composition, microstructure and relative density were studied. Permeability, magnetic loss and AC resistivity were measured in the frequency range of 1 kHz–10 MHz. Permeability and AC resistivity were found to increase and loss decreased with Sm substitution up to x=0.05. Saturation magnetization also increased up to that substitution limit. Observed variations in electromagnetic properties have been explained.
