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 their nano-sized and dispersed state, which is, up to date, a difficult and imprecise task.
