Abstract
The Sm–Fe/polyvinylidene fluoride (PVDF) heterostructural film was prepared by depositing Sm–Fe nanoclusters onto the flexible PVDF film using cluster beam deposition method. The PVDF film acts as both piezoelectric layer and substrate. The heterostructural film showed the well-defined microstructures in which the Sm–Fe layer was assembled by the nanoparticles, and the interface between Sm–Fe and PVDF layers was clear. The heterostructural film possessed evident magnetic anisotropy with in-plane easy axis and exhibited large voltage output under the magnetic bias. Such flexible heterostructural film with large magnetoelectric output makes it promising to be widely used for the weak magnetic-field detection.Keywords
