Polycrystalline NiZn ferrites with the chemical formula (Ni0.3Zn0.7)1-xBexFe2O 4with Be substituent ion x=0, 0.05, 0.1, and 0.25 have been prepared by the ceramic method. The intrinsic and certain extrinsic magnetic properties such as the coercivity Hc, initial permeability ??iand hysteresis loops of the ferrites have been measured and discussed from the point of view of the substituting element...
