Abstract: The polycrystalline ferrites with the compositions Mn0.58+x/2 Zn0.37+x/2 TixFe2.05-2x O4 and Mn0.58+x/2 Zn0.37+x/2 ZrxFe2.05-2x O4 where x = 0.0, 0.1, 0.2, 0.3 and 0.4 have been prepared. The variations in lattice parameter, saturation magnetization, Curie temperature and initial permeability are explained on the basis of the distribution of the dopant cations among the tetrahedral and octahedral sites of the ferrite lattice. Theoretically evaluated lattice constant values are compared with the experimentally obtained lattice constant values and are in good agreement. The observations indicate the presence of non- collinear magnetic spin order on B sites. Magnetic moment and Yafet- Kittel angle values are also evaluated.
