Villari effect

This method is based on the Villari effect applying a uniaxial stress to a ferromagnetic substance induces a magnetoelastic anisotropy which may modify all the parameters of its magnetisation curve, e.g. magnetic susceptibility, coercive force, and so on. Some experimental techniques to measure the strain-induced anisotropy are discussed shortly below. 

Other methods based on the Villari effect can be found in the paper by Lachovicz and Szymczak(1984). 

Villari effect Changes in the magnetic properties of a material when pressure is applied to the material. Also known as the magnetomechanical effect.
