Proximity effects in Ferromagnet/Superconductor Heterostructures (F/S-H) have demonstrated high potential for development of new devices for spintronic and quantum computing application. SrRuO3 (SRO) has attracted much attention among transition metal oxides for being the only 4d oxide to show itinerant ferromagnetism and metallic conductivity. In this work, we are characterizing the crystal structure as well the magnetic properties of SRO thin films for further application in F/S-H with YBa2Cu3O7−x superconducting films. The samples were prepared on STO (001) single crystals by High-Oxygen Pressure Sputtering. SRO thin films are epitaxial and have smooth surface. Magnetometry indicate that samples have out-of-plane magnetic anisotropy and paramagnetic-ferromagnetic transition at approximately 150 K, which corresponds to the SRO with Ru4+ Curie temperature, and two transitions at lower temperatures, that may be related to another Ru oxidation state. The samples stoichiometry will be further investigated by Rutherford Backscattering Spectroscopy. |
