abstract = {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.},
