Converse Magnetoelectric Effect in Pb(In_(1/2)Nb_(1/2))O_3-PbTiO_3/NiFe_2O_4 Laminate Composite

摘要

Pb(In_(1/2)Nb_(1/2))O_3-PbTiO_3/NiFe_2O_4 bilayer laminate composite was prepared and the converse magnetoelectric (CME) effect was investigated using a laboratory made experimental arrangement. The CME was measured by applying an ac voltage to the piezoelectric phase and the induced magnetization from the magnetic phase was observed with a pick up coil. CME studies were performed at both resonant and non resonant frequencies. The result shows the maximum value of CME coefficient (α_(CME)) of 116.4 mG/V at resonance frequency (230.1 kHz) under external bias field of 100 Oe. This composite can be used in electric field controlled magnetic transducers.
