N2  - In this work a series of samples were prepared by using standard ceramic technique. The prepared samples were classified into two groups. In the first group metal oxides were mixed in a stoichiometric ratio according to the formula Ni₁- {u036F} - Mg {u036F} Fe₂ O₄{u₂₂₆₄} where 0.0 {u2264}x{u2264}0.7 and well grounded in a planetary agate mortar for 3hs. The mixture wass pressed into pellets form using uniaxial press of pressure 1.9 x 10⁸ NM⁻²
