Abstract

Epitaxial SrRuO3 films were prepared on (001) SrTiO3 substrates by pulsed laser deposition. The film structure was characterized by 4-circle x-ray diffraction and the electrical behavior by temperature dependent resistivity measurements. With variations in the deposition conditions, significant changes in both structural and electrical properties were observed. When deposited under conditions favoring appreciable energetic bombardment, the SrRuO3 films on SrTiO3 exhibited extended in and out-of-plane lattice constants and increased values of resistivity; in addition, a depression of the Curie temperature was measured. SrRuO3 deposited under less aggressive conditions displayed structures and properties more similar to those associated with bulk crystals.
