Abstract
The NiCd ferrites with Fe excess in comparison with stoichiometry composition and with Fe excess amount substituting by Cr, moreover containing small amount of Co are prepared. The formation of preminvar effect and uniaxial induced anisotropy in these ferrites are examined under the heat treatment with and without magnetic field. The appearence of uniaxial induced anisotropy causes unexpected changes of some magnetic and electric properties of ferrites.
