AB  - Heterostructures (HS) based on superconductors and ferromagnets ex- hibit strong potential for innovating devices in spintronics and quan- tum computing applications. SrRuO3 (SRO) has attracted much at- tention 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 su- perconductors with a large variety of applications. We report struc- tural, morphological, magnetic and magnetotransport characterization of YBCO/SRO (S1) and SRO/YBCO (S2) HS prepared on low mis- cut SrTiO3 (001) single crystals by high oxygen pressure sputtering. The HS exhibit epitaxial growth with good crystal quality and sharp interfaces, with critical temperatures of 87.5 K and 57 K for S1 and S2, respectively, both reduced in relation to YBCO (91 K). The inver- sion of the magnetoresistance peak at temperatures around the onset of superconductivity strongly indicates the occurrence of a proximity effect at the interface. The HS will be further examined by Polarized Neutron Reflectometry and X-ray Magnetic Circular Dichroism.
