The authors report a giant topological Hall effect at room temperature in permalloy/La${}_{0.65}$Sr${}_{0.35}$MnO${}_{3}$ (Py/LSMO) heterostructures, with resistivity reaching ~2.8 \ensuremath{\mu}\ensuremath{\Omega}\ifmmode\cdot\else\textperiodcentered\fi{}cm, far exceeding that of single-layer Py. The effect arises from the interplay of LSMO ferromagnetism and Rashba spin--orbit coupling at the broken-symmetry interface. Magnetic imaging reveals the presence of skyrmion-like spin textures, which are further tunable with a ferroelectric spacer, as corroborated by theoretical modeling. These findings establish Py/LSMO heterostructures as a promising platform to manipulate interfacial spin textures and advance next-generation spintronic technologies.
