摘要：
Polarized Raman spectra of a heteroepitaxial barium strontium titanate film on a MgO substrate were studied in an external electric field applied perpendicular to the direction of spontaneous polarization. The partial depolarization observed in the spectra indicates the electric-field-induced reduction of the symmetry of the crystal lattice.
