Determination of the magnetostrictive response of nanoparticles via magnetoelectric measurements.

It is successfully demonstrated that nanoparticle's magnetostriction can be accurately determined based on the magnetoelectric effect measured on polymeric composite materials. This represents a novel, simple and versatile method for the determination of particle's magnetostriction at the nano scale and in their dispersed state, which has been, up to now, a difficult and imprecise task.
