Abstract:Zn2+ doped cobalt ferrite and the Co0. 8Zn0. 2Fe2O4/(Ba0. 85Ca0. 15)(Zr0. 1Ti0. 9)O3 magnetoelectric composite thin films (CZFO/BCZT) were prepared via a Sol-gel process. The samples were characterized by X-ray diffraction (XRD), field-emission scanning electron microscope (FE-SEM), Raman spectrometer and vibrating sample magnetometer (VSM). The results show the CZFO thin film deposited on Pt(111)/Ti/SiO2/Si substrate exhibit a good crystalline quality with pure phase and no obvious preferred orientation under a compressive strain state. The saturation magnetization (Ms) and coercive field (Hc) are 405 emu/cm3 and 780×79. 577 A/m respectively with the external magnetic field applied parallel to the thin film surface. The CZFO thin film, by contrast, exhibit a higher Hc compared with the CZFO powder. The magnetoelectric composite thin films also exhibit good crystalline quality and obvious interface.
