Transverse Magnetic Response from Orbitally Polarized Cooper Pairs in Elemental Superconductors
Gabor Csire, Maria Teresa Mercaldo, Balazs Ujfalussy +2
We demonstrate how crystalline symmetry lowering, as for instance through strain, allows elemental superconductors such as vanadium and niobium to realize spin-singlet orbitally po…
Directional Andreev-Reflection Signatures of Inter-Orbital Pairing in SrRuO
