Magnetostriction via Magnetoelectricity: Using Magnetoelectric Response to Determine the Magnetostriction Characteristics of Composite Multiferroics

We propose a new method for determining the magnetostriction characteristics of composite multiferroics by measuring the magnetoelectric (ME) response of the material structure. It is established that the integral characteristic of the ME effect coincides to within a constant factor with the magnetostriction curve. The results of an experimental investigation of the physical properties of volume composites based on lead zirconate titanate (PZT) and nickel ferrite spinel are presented. The field dependence of the ME voltage coefficient was used to determine magnetostriction curves of composite structures containing 10–70 wt % ferrospinel.
