Abstract

Local polarization processes in BaTi_{1 – x}Zr_xO₃ thin films are studied using contact conductive scanning probe microscopy and piezoelectric response microscopy. The relationship between the direction of the created domains and the magnitude of the flowing currents is established. The value of the residual polarization is found. Using scanning probe microscopy, the hysteresis loop is measured and the values of the piezoelectric modulus d_zz and coercive field E_c for these films are determined.
