Abstract

We investigated the polarized Raman spectra of a strain-free, unipolar-axis oriented tetragonal Pb (Zr,Ti) O₃ thick epitaxial film. We evaluated the single crystal-like selection rules of the A₁-and E-symmetry components, and found an anomalous behavior in the angular dependence of the A₁ (1TO)-mode intensity similar to that observed in high-T _c superconductor single crystals. Raman tensor analyses of the A ₁ (1TO) mode revealed complex phases may exist between two independent Raman-tensor components even in the single 180° domain state.
