Manganese and cadmium co-substituted lithium ferrite having the general formulae Li0.35Cd0.3MnxFe2.35-xO4 + 0.10 wt% Bi2O3 with x=0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 has been prepared by standard ceramic technique. M-H curves of all samples have been determined by using vibrating sample magnetometer (VSM). The highest saturation magnetization 79emu/g is observed in Li0.35Cd0.3Fe2.35O4 (Mn = 0) and it decreases with increase in manganese content in the compound. It is observed that the value of initial permeability increases to maximum value similar to 230 for Mn = 0.4 and then decreases with further increase in Mn contents. The dc resistivity of all samples is found in the range of 10(7) Omega cm. (C) 2009 Published by Elsevier B.V.
