Spin-singlet to triplet Cooper pair converter interface

Abstract Combining magnetic and superconducting functionalities enables lower energy spin transfer switching in quantum computing information storage, owing to the dissipationless nature of quasi-particle mediated supercurrents. Here, we put forward a system where emergent spin-ordering diffusion Cooper pairs are achieved at non-intrinsically nor metallo-molecular interface. Electron transport, magnetometry low-energy muon rotation used probe time-reversal symmetry breaking these structures. By comparing Meissner expulsion including Cu/C 60 spin-converter interface one without, observe paramagnetic contribution that can be explained due conversion spin-singlet pair states into odd-frequency triplet states. These results demonstrate potential interfaces achieve singlet conversion, capability not present either metal or molecule separately could generation controlled polarised currents.
