Influence of the elastically stressed state of interfaces on the magnetoelectric properties of ferromagnetic/ferroelectric layered structures

In the layered ferromagnetic/ferroelectric structures in the form of cobalt, nickel or permendur layer on a ferroelectric substrate of lead zirconate titanate obtained by ion-beam sputtering – deposition, relative strains due to mismatch of crystal lattices of mating materials at the metal/substrate in-terface make a more noticeable contribution to the magnetoelectric response than those associated both with the magnetostriction of the ferromagnetic layer and with the piezoelectric effect of the ferroelectric substrate. The structures obtained are characterized by the thermal stability and reproducibility of magnetoelectric characteristics and can be used as converters of magnetic and electrical quantities, for example, in magnetic field sensors and actuators.
