    Frequency dependence in the piezoresponse force microscopy of dense piezoceramics

    Images of the piezoresponses (PRs) in the frequency range of 15–2500 kHz are obtained for dense polarized PCR-1 piezoceramics. It is shown that in the region of resonance, the dependence of PR amplitudes on fr...

    Lattice deformation in thin BiFeO3 and Ba0.8Sr0.2TiO3 epitaxial films on (001)MgO single crystalline substrates

    Bi0.98Nd0.02FeO3 (BNFO) and Ba0.8Sr0.2TiO3 (BST) epitaxial films produced by rf cathode sputtering on (001)MgO substrates are studied by means of XRD. The thickness dependences of uniform lattice deformations and...
