Theoretical Cation distribution for cubic spinel ferrites was suggested on basis of electrical configuration expectations and cation site preferences. Cation distribution suggested was in good agreement with experimental results obtained from VSM and XRD. Values of theoretically calculated magnetic moment, coercivity and magnetization are in good agreement with experimental data obtained from VSM. Maximum saturation magnetization of 37.7emu/gm is obtained for sample Co_0.7Mn_0.3Fe₂O₄</span></span></span><span lang="EN-US" style="font-size:12.0pt"><span style="line-height:200%"><span linotype="" palatino="" style="font-family:">at magnetic field of 5K Oe.
