Abstract
The variation of susceptibility with temperature of the Zn x Mg1−x Fe2O4 system has been obtained between 300 K and the Neél temperature at a constant magnetic field of 7.0 Oe for x=0.0 to 0.7. Through the magnetization measurements of this Mg-Zn ferrite system the variation of saturation magnetization with zinc concentration was determined in gaining information about the Yafet-Kittel angles in the system for x⩽0.9 at 298 K. The observations indicate the existence of a Yafet-Kittel type of magnetic ordering in the system. A molecular field analysis of the Y-K spin ordering using a three sublattice model is shown to explain the experimental data satisfactorily. For the sake of verification, Neél temperatures of Mg-Zn ferrites were also determined from Mössbauer studies.
