The c-domain fractions of the PZT films with no electrode layer, with a 50 nm electrode layer between the film and the substrate, and with 50 nm electrode layers on top and bottom of the PZT film were found to be equal. This means that depolarizing fields do not affect the polydomain structure of the film. Calculations of the in-plane strains based on the lattice parameters of the La0.5Sr0.5CoO3 (LSCO) layer in the above configurations led to the conclusion that the bottom electrode layer is coherently strained to match the substrate. © 1999 Materials Research Society.}, year = {1999}, journal = {Materials Research Society Symposium - Proceedings}, volume = {541}, pages = {357-362}, issn = {02729172}, note = {cited By 0}, language = {eng}, }
