Abstract

We have reported the epitaxial growth and the electric/magnetic properties of SrRuO₃ and (La_0.67Sr_0.33)MnO₃ thin films on Ba(Ti_0.925Zr_0.075)O₃ substrates. The dielectric constant and thermal expansion of Ba(Ti_0.925Zr _0.075)O₃ exhibited hysteretic jumps at the structural transition temperatures. Near the rhombohedral to orthorhombic structural transition temperature of Ba(Ti_0.925Zr_0.075)O₃, which occurs at ∼33 C, we have observed a drastic jump of resistivity and magnetization of the thin films. These results suggest that epitaxial perovskite oxide thin films on Ba(Ti_0.925Zr_0.075)O₃ substrates should be quite useful for the strain-induced changes of physical properties near room temperature.
