Abstract

This study examined the effect of various types of epitaxial strain on the magnetic properties of SrRuO3 thin films. Epitaxial SrTiO3(001), SrTiO3(110), and SrTiO3(111) substrates were used to apply different crystal symmetries to the grown films. The films were grown using pulsed laser deposition. The X-ray diffraction patterns of the films grown under optimum conditions showed very clear peaks for the SrRuO3 film and SrTiO3 substrates. The saturated magnetic moment at 5 K after 7 Tesla field cooling was 1.2-1.4μB/Ru. The magnetic easy axis for all three types of films was along the surface normal. The magnetic transition temperature for the SrRuO3 film with lower symmetry was slightly larger than the SrRuO3 film with higher symmetry.
