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. On the other side, YBa2Cu3O7-x (YBCO) is one
of the most studied high Tc superconductors with a large
variety of application for devices [1, 2]. In this work, we
aim to characterize the crystal structure as well the
magnetic and transport properties of SRO thin films and
SRO/YBCO heterostructure, with further investigation of
proximity effects with Neutron Scattering and X-ray
spectroscopy. The samples were prepared on low miscut SrTiO3
(001) single crystals by High-Oxygen Pressure Sputtering.
SRO thin films are epitaxial and have low surface roughness.
Magnetometry indicates that samples have out-of-plane
magnetic anisotropy and paramagnetic-ferromagnetic
transition at approximately 150 K. Two other transitions
were observed at lower temperatures, that might be related
to the polymorphism of the SRO crystal structure [3, 4].
Preliminary results of a YBCO(100nm)/SRO(50nm)
heterostructure point to an epitaxial sample with good
crystal quality and low surface roughness. In comparison to
a YBCO(100nm) thin film, the YBCO(100nm)/SRO(50nm)
heterostructure shows a reduction of the transition
temperature Tc to the superconducting phase, which can be
related to proximity effects. The latter results will be
further examined, and other characterizations will be
performed to investigate the presence of proximity effects
on YBCO/SRO heterostructures.},
