The effect of Zn and Ti on the magnetic, power loss and structural properties of Li0.5ZnxTixMn0.05Fe2.45−2xO4 ferrites (x=0.0 to 0.30 in step of 0.05)+0.5 wt% Bi2O3, prepared by standard ceramic technique, has been investigated. Complex permeability (μ*=μ′−jμ″) has been analyzed at room temperature in frequency range from 1 to 103 MHz. It was found an enhancement in permeability with Ti and Zn concentration in Li0.5ZnxTixMn0.05Fe2.45−2xO4 and exhibits the maximum value 106 for x=0.20 sample. Complex permeability of these ferrites exhibits stable frequency response up to 7 MHz beyond which the real part decreases sharply and imaginary part increases to have a peak at the relaxation frequency. Power loss measurements have been carried out in induction condition (B=10 mT) in frequency range of 50 kHz to 3 MHz. Power loss has been found to be quite low with the substitution of Ti and Zn in lithium ferrite.
