High magnetostriction coefficient of two-stage sintered cobalt ferrite

What is it about?

Magnetostrictive materials are smart materials for applications in sensors and actuators. Cobalt ferrite is a suitable material for such applications. In this publication, it is shown that high magnetostrcition coefficient can be obtained when nanosized cobalt ferrite powder is sintered at relatively low temperatures by a two-stage method of sintering, thereby reducing the cost of production, along with the advantages that the material is ceramic and cheaper, for various applications.

Why is it important?

Very high magnetostriction coefficient is obtained for polycrystalline cobalt ferrite when sintered from nanomaterial, at relatively lower temperatures, by the method of two-stage sintering.
