摘要: The effect of Zr-substitution on the physical and magnetic properties Li0.3+0.5xZn0.4ZrxFe2.3-1.5xO4 ferrites (x=0.0, 0.01, 0.02, 0.03 0.05), prepared by standard ceramic method, has been studied. It is found that saturation magnetization increases up to x=0.02 then it decreases. On other hand, initial permeability increased while Curie temperature remained almost constant with increasing x. behavior coercivity remanence ratio was discussed. composition dependence dc electrical resistivity support hopping conduction mechanism.
