Abstract
Magnetoelectric materials exhibit change in dielectric
polarization on application of magnetic field or change in magnetization on
application of electric field. These materials are extremely promising for
applications such as actuator, transducer and storage devices. Magnetoelectric effect is a product property implying that
the effect is absent in the individual phases but observed in the composite. In
past 30 years several magnetoelectric materials and
composite geometries have been reported in literature,
however the magnitude of the magnetoelectric
coefficient is still quite low. We have recently found the high performance magnetoelectric composition in the Pb(Zr0.52Ti0.48)O3 – x
NiFe1.9Mn0.1O4 system. This presentation will describe the physics of the magnetoelectric materials and report the properties and
microstructure of our composition.
