摘要

The magnetic and microwave properties of a heterostructure composing of a composition-graded FeCoTa film and a [Pb(Mg1/3Nb2/3)O3]0.68-[PbTiO3]0.32(011) substrate were investigated with respect to a varied applied electric field. For the as-deposited sample in the initial unpoled state, the resonance frequency is 7.2 GHz and it is suddenly increased to 8.4 GHz when the applied electric field reaches 2 kV/cm. Then upon the changing of the electric field from 6 kV/cm to −6 kV/cm, the resonance frequency is varied in the range from 8.4 GHz to 9.2 GHz. The resonance frequency can only be reset back to the lower level with the value of 7.6 GHz through the depolarization process. The results are interpreted in terms of the change in ferroelectric domain structures leading to the variation of the stress-induced magnetic anisotropy, which is experimentally verified by the magnetic and microwave behaviors after depolarization.
