Signature of Orbital Driven Finite Momentum Pairing in a 3D Ising Superconductor

ORAL

Abstract

Finite momentum pairing, an exotic superconducting state, can exist in systems with strong Ising spin-orbit coupling. 4Hb-TaS2,

one such candidate material, shows C2 to C6 symmetry transition in magnetoresistance below superconducting Tc with increasing

strength in-plane magnetic field, indicative of the orbital field-driven anisotropic phase sourced from magneto-electric effect

respected by the symmetries. Presence of this magnetoelectric FMP phase assures breaking of the observed rotational symmetries in

the anisotropy phase
