%X Mixed ferrites Cr1.05 Li0.5 Mg x Fe1.45-(2/3)x O4 (0 ¡Ü x ¡Ü 0.4) doped with Magnesium have been studied using x-ray diffraction, M ssbauer spectroscopy and magnetic measurements. X-ray diffraction patterns show that all samples have single phase cubic spinel structure. The temperature-dependent magnetic measurements revealed that magnetic compensation disappears when Fe3+ in A-site is partially replaced by Mg2+. Moreover, below the compensation temperature the observed magnetic moment of these ferrites increases with magnesium content. The magnetization data at all concentrations are discussed in the light of N¨¦el¡¯s molecular field model taking into account the cations distribution obtained using the analysis of M ssbauer spectra.
