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.
