摘要：
We report the fabrication of 60Ba(Zr0.2Ti0.8)O-3-40(Ba0.7Ca0.3TiO3)/Fe65Co35 (60BZT-40BCT/Fe65Co35) films on Pt/Ti/SiO2/Si substrates. The 60BZT-40BCT films exhibit well defined piezoelectric properties and the magnetic properties of Fe65Co35 films were characterized, which suggests the multiferroic nature of the films. The transport characteristics of Fe65Co35 films could be modified when the samples are subjected to a bias voltage along the thickness direction for 60BZT-40BCT/Fe65Co35 films, which manifests itself in the variation of current-voltage (I-V) curves of Fe65Co35 films under the influence of applied bias voltage. This produces more than an order of magnitude change in resistance. The manipulation could be attributed to the strain-mediated coupling and the charge accumulation and depletion at the interface.
