Abstract
Lead free magnetoelectric laminates has been prepared by sandwiching Sodium Bismuth Titanate (Na0.5Bi0.5TiO3) between two Tb0.3Dy0.7Fe1.95 (TDF) by epoxy bonding. The piezoelectric material Sodium Bismuth Titanate (Na0.5Bi0.5TiO3) has been prepared by conventional solid state double sintering method and the magnetostrictive material, Tb0.3Dy0.7Fe1.95 (TDF) by vacuum induction melting process. NBT showed a saturated ferroelectric hysteresis behavior with the values of Ps=22.24μC/cm2, Ec=41kV/cm and Pr=27μC/cm2. The piezoelectric charge coefficient (d33) measured for NBT was 102pC/N. Magnetization versus magnetic field measurements were performed in longitudinal (L) and transverse (T) modes of TDF specimen that showed ferromagnetic hysteresis behavior. The magnetostriction of 950ppm at 4kOe and static strain coefficient of 0.37×10−6kOe−1 at 1kOe magnetic field were recorded for Tb0.3Dy0.7Fe1.95. The magnetoelectric output was measured in L and T modes for the different NBT thickness of 1.0, 1.5 and 2mm with TDF thickness of 1.5mm. The high magnetoelectric coefficient (α) was found to be 0.08mV/cmOe (L mode) and 0.13mV/cmOe (T mode) for the NBT/TDF laminates with 1.0mm thick NBT.
