Dielectric behaviour in magnetoelectric composites

The magnetoelectric composites, namely (1−x)Ni0.5Co0.5Fe2O4, −xBa0.8Pb0.2TiO3 (x-volume fraction) were prepared by standard ceramic method. A detailed study on the dielectric properties was done presuming that the magnetoelectric interactions between constituent ferrite and ferroelectric phases may result in various anomalies in the dielectric behaviour of these composites. The results obtained are summarized in the conclusion part of the Letter. The observations are unlike the dielectric behaviour of other ME composites studied earlier.
