      abstract     = {Proximity effects in Ferromagnet/Superconductor
                      Heterostructures have demonstrated high potential for the
                      development of new devices for spintronic and quantum
                      computing applications. 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 applications [1, 2]. In this work, we report
                      magnetotransport results of YBCO(100 nm)/SRO(50 nm) bilayer
                      heterostructure prepared on low miscut SrTiO3 (001) single
                      crystals by high oxygen pressure sputtering. Preliminary
                      results point to an epitaxial sample with good crystal
                      quality and low surface roughness. The critical temperature
                      of 87.8 K is reduced in relation to the YBCO reference
                      sample (91 K). Around the superconductivity onset several
                      remarkable features take place while sweeping up and down at
                      5T external magnetic field applied in-plane and out-of-plane
                      in relation to the sample surface. The inversion of the
                      magnetoresistance peak for temperatures of 89 K < T < 92 K
                      is a strong indication that a proximity effect takes place
                      at the interface and opens a discussion of how to model such
                      kind of behavior. This result will be further examined by
                      means of Polarized Neutron Reflectometry and X-ray Magnetic
