Self-assembled nanocomposite Pb(Zr0.52Ti0.48)O3-NiFe2O4 films were prepared on the(001)-oriented MgAl2O4substrates by a 90° off-axis magnetron sputtering method.The influences of substrate temperature,argon over oxygen ratio and sputtering power on the structure and properties of PZT-NFO nanocomposite films were studied.The optimal growth conditions are substrate temperature of 800 ℃,argon over oxygen ratio of 1:1 and sputtering power of 160 W.XRD studies reveal that the PZT-NFO film is epitaxial along both...
