Abstract

A lead-free magnetoelectric (ME) laminate composite consisting of thickness-polarized piezoelectric Mn-doped Na_0.5Bi_0.5TiO₃-BaTiO₃ single crystal and length-magnetized magnetostrictive Tb_0.3Dy_0.7Fe_1.92 alloy (L-T mode), have been fabricated and its ME properties has been evaluated. The results revealed that the lead-free composite has linear magnetic-electric response in excess of 1.32 V/cm Oe at low frequency over the range of 10^-7 T < H_ac < 10^-3 T, the ME coefficient dramatically increases and reaches the maximized value of 18 V/cm Oe near the resonance frequency of 160 kHz. This heterostructure opens up the possibility for environment-friendly magnetic sensors.
