Abstract

The coercivity of the plasma-sprayed MnZn ferrite films decreases significantly after annealing in air at the temperature range of 500-800°C. Magnetostriction and surface stress changes incurred in these ferrite films after the annealing process has been measured. It is found that the effects of the external stress on the magnetic properties of the plasma-sprayed MnZn ferrite films are minor. The coercivity mechanism arising from the magnetoelastic effects due to the nonzero magnetostriction has been analyzed to be small and is not dominant in controlling the magnetization process in these ferrite films.
