Abstract

The magnetostriction of a number of copper-containing ferrite spinels was measured. In all the ferrites studied, below room temperature, |λ‖| was found to decrease with temperature. It is conjectured that this decrease in |λ‖| originates from an increase in the degree of covalency among the Cu2+-O2− ions, which, in turn, reduces their spin-orbit coupling.
