%X The effect of Al-substitution on the physical, IR spectra and magnetic properties of Mn0.5Ni0.1Zn0.4AlxFe2-xO4 (x=0 to x=0.15, with step= 0.025) ferrites, prepared by conventional ceramic method, has been studied. The analysis of IR spectrum indicated the distribution of Al-ions between both A and B-sites. On Al substitution, the values of saturation magnetization, initial permeability and Curie temperature were increased. The dc resistivity is also increased with increasing Al-content. Such results are promising ones for the high frequency applications.
