Magnetoelastic Villari effect in Mn–Zn ferrites

Adam Bieńkowski

Abstract

The relationship between magnetic induction B, and compressive stress −σ in Mn–Zn ferrites, of very low magnetostrictive constant λs, were investigated. The Villari effect and its technical importance is discussed. It is shown that in Mn–Zn ferrites, with λs≈0, the Villari point occurs for σ≈0 and that these ferrites exhibit, for σ≫0, considerable magnetoelastic sensitivity — in spite of their small λs value. Hence, a low magnetostriction constant λs does not exclude the possibility to apply such materials in magnetoelastic sensors.
