| Abstract Scope |
The integration of superconducting and ferroelectric materials into multilayered thin films presents a promising avenue for tunable photonic and quantum devices. In this work, we investigate epitaxially grown YBa₂Cu₃O₇₋δ (YBCO) and BaTiO₃ (BTO) heterostructures synthesized via pulsed laser deposition, focusing on their interfacial structure and emergent magnetic properties. X-ray diffraction, reflectometry, and atomic force microscopy confirm high-quality film growth with distinct layer formation. However, due to low X-ray contrast between layers, neutron reflectometry (NR) is employed to resolve the chemical and magnetic profile of the buried interface. We aim to probe defect-induced magnetism in the BTO layer and magnetic flux penetration in YBCO below its critical temperature. Preliminary measurements suggest robust ferroelectric and superconducting properties are retained in the bilayer. By combining NR/PNR with complementary X-ray and magnetic characterization, we aim to elucidate the structural-magnetic interplay at the interface, paving the way for next-generation low-energy electronic applications. |
