Abstract
Neutron powder diffraction experiments have been carried out on two interesting perovskite compounds, Sr2RuO4 (K2NiF4 structure) and SrRuO3 (distorted perovskite), both of which are used as substrates for the growth of high-temperature superconducting thin films. The powder diffraction data have been refined at high and low temperatures to obtain lattice parameters and the lattice mismatch between these compounds and YBa2Cu3O7 over a wide temperature range is found to be good. No evidence has been found for any lattice distortions between 5 and 973 K in Sr2RuO4 and between 100 and 300 K in SrRuO3.
