Tunable critical field in Rashba superconductor thin-films
L. A. B. Olde Olthof, J. R. Weggemans, G. Kimbell +2
The upper critical field in type II superconductors is limited by the Pauli paramagnetic limit. In superconductors with strong Rashba spin-orbit coupling this limit can be overcome…
Spin-orbit coupling suppression and singlet-state blocking of spin-triplet Cooper pairs
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…
Spin-transport in superconductors
K. Ohnishi, S. Komori, G. Yang +5
Spin-transport in superconductors is a subject of fundamental and technical importance with the potential for applications in superconducting-based cryogenic memory and logic. Rese…
Electronic spectral function in fractionalized Pair Density Wave scenario
Maxence Grandadam, Debmalya Chakraborty, Xavier Montiel +1
Studies of the electronic spectral function in cuprates by Angle-Resolved Photo-Emission Spectroscopy reveal unusual features in the pseudogap phase that persist in the superconduc…
Tunable pure spin supercurrents and the demonstration of a superconducting spin-wave device
Kun-Rok Jeon, Xavier Montiel, Sachio Komori +7
Recent ferromagnetic resonance experiments and theory of Pt/Nb/Ni8Fe2 proximity-coupled structures strongly suggest that spin-orbit coupling (SOC) in Pt in conjunction with a magne…
Generating superconducting vortices via spin-orbit coupling
L. A. B. Olde Olthof, X. Montiel, J. W. A. Robinson +1
Spin-orbit coupling (SOC) is known to play an important role in superconductor/ferromagnet heterostructures. Here we demonstrate that SOC results in the spontaneous generation of v…
