制备了Pb（Zr，Ti）O3/CoFe 2 O 4/Pb（Zr，Ti）O3异质结薄膜，研究了其磁电输出随循环极化的变化。薄膜经45 MV/m、循环次数为2.2×108次的循环极化后，其巨磁电输出比原始薄膜提高了约一个数量级。我们认为，在这种显着的磁电增强的异质结构中的氧空位迁移和极化的电荷在CoFe_2O_4层中发挥重要作用。
The Pb(Zr,Ti)O3/CoFe2O4/Pb(Zr,Ti)O3 heterostructural film was prepared and the variation in its magnetoelectric output with the cycling electric polarization was investigated. The giant magnetoelectric output, which was about one order enhancement in magnitude compared with the original film, was observed after the film was subjected to the cycling electric polarization with the strength of 45 MV/m and cycling number of ∼2.2×108. We consider that both oxygen vacancy migration in the heterostructure and the polarized electric charges in the CoFe2O4 layer play important roles in such significant magnetoelectric enhancement.
