Abstract

Ferromagnetic shape memory alloy Ni49Fe18Ga27Co6 was used in a laminated composite with Pb(Zr0.52Ti0.48)O3 for studying the converse magnetoelectric (CME) effect. The CME properties with the frequency of driving electric voltage, bias magnetic field, and dc bias electric voltages were investigated in detail. A large value of αB of 1.05 G/V at the resonance frequency 89 kHz is observed under a low optimum Hbias of 100 Oe. The maximum values of αB at 1 kHz can be tuned from 8.7 to 25 mG/V by increasing dc voltage bias from −100 to 100 V, exhibiting a giant tunable range in αB values. This composite exhibits promising applications in electrically controlled magnetic force devices.

► An alternative method in magnetization manipulation is proposed in this paper. ► We constructed Ni49Fe18Ga27Co6/Pb(Zr0.52Ti0.48)O3 laminated magnetoelectric composite. ► A large value of αB of 1.05 G/V s observed under a low optimum Hbias of 100 Oe. ► The maximum values of αBcan be effectively tuned by additional dc voltage bias.
