Magnetic Properties of SrRuO₃ Epitaxial Thin Film Grown on KTaO₃ (001) Substrate

We investigated the magnetic properties of SrRuO3 epitaxial thin film synthesized by using pulsed laser deposition on KTaO3 (001) substrate. X-ray reciprocal space mapping scans showed clear peaks demonstrating high quality, tensile strain with increased unitcell volume, and relaxed growth behavior. Magnetization data shows that the magnetization of the SrRuO3 film with magnetic field along the in-plane direction was larger than one with magnetic field along surface-normal direction.
