Influence of Permeability and D₃₃ on Fega/PZT/Fega Magnetoelectric Effect

Abstract:

FeGa/PZT/FeGa magnetoelectric device was prepared and the ME effect examined. FeGa alloys was made by different processing method. The results showed that the domains and texturing of FeGa had a great impact on both magnetic and ME performance. The permeability and d₃₃ (the differential of magnetostrictive coefficient) of FeGa differed with processing. It was found that FeGa rolled sheets had good toughness, d₃₃ could reach 2.7 ppm/Oe, and magnetic permeability reached 180 H/m. The device made of FeGa rolled sheets also had a large output (18 V/cm Oe) and low bias field (~ 96 Oe).
