Realisation of de Gennes Absolute Superconducting Switch with a Heavy Metal Interface
Hisakazu Matsuki, Alberto Hijano, Grzegorz P. Mazur +13
In 1966, Pierre-Gilles de Gennes proposed a non-volatile mechanism for switching superconductivity on and off in a magnetic device. This involved a superconductor (S) sandwiched be…
Unveiling unconventional magnetism at the surface of SrRuO
Rosalba Fittipaldi, Roman Hartmann, Maria Teresa Mercaldo +23
Materials with strongly correlated electrons exhibit physical properties that are often difficult to predict as they result from the interactions of large numbers of electrons comb…
Quantized conductance in split gate superconducting quantum point contacts with InGaAs semiconducting two-dimensional electron systems

Sachio Komori, James Devine-Stoneman, Kohei Ohnishi +10
An inhomogeneous magnetic exchange field at a superconductor/ferromagnet interface converts spin-singlet Cooper pairs to a spin-aligned (i.e. spin-polarized) triplet state. Althoug…
