Abstract
Epitaxial SrBi2Nb2O9 films were grown by laser ablation on (001)YBa2Cu 3O7-delta/(100)SrTiO3 and (001)NdGaO3, with c axis normal to the subst rate plane. The SrBi2Nb2O9 films were grown in a layer-by-layer regime on NdGaO3 substrates in 25-Angstrom steps at a condensation temperatu re of 700 degrees C, Microinclusions of secondary phases and a-oriente d grains were observed to exist on the surface of (001)SrBi2Nb2O9 film s grown on (001)YBa2Cu3O7-delta/(100)SrTiO3. The dielectric permittivi ty of the SrBi2Nb2O9 films measured along the c axis is 123 (T = 300 K , f = 100 kHz), and tan delta approximate to 0.04. (C) 1997 American I nstitute of Physics.
