Magnetoelectric effect of polymer electrolyte composites with Terfenol-D and lead zirconate titanate inclusions

The magnetoelectric effects of three-phase composites in 0-0-3 connectivity were investigated. The composites consist of particulate Terfenol-D and lead zirconate titanate blended in different polymer matrices. The magnetoelectric coefficient alpha(q), which is the charge density change in response to a change in the applied magnetic field, of the samples was measured under short circuit condition. The results show that the alpha(q) of the samples with an electrolytic polymer matrix is larger than that of the samples with an insulating matrix, while samples with an ion-doped electrolytic polymer matrix exhibit the largest alpha(q). These results conform with the expectation that higher matrix conductivity has an effect of enhancing the magnetoelectric signals.
