Ni substitution effect on the structure, magnetization, resistivity and permeability of zinc ferrites

Abstract

Increase in the spontaneous magnetization up to <italic>x</italic> &lt; 0.5 is a sequence of appearance of the additional magnetic moment of 2 <italic>μ</italic>_B of the Ni²⁺ cations in tetrahedral positions. For <italic>x</italic> &gt; 0.5, the moment decreases in octahedral positions and the spontaneous magnetization also decreases.
