Two-Component Superconductivity of Heavy Fermionic Material UPt3
Abstract
The theory of the Abrikosov lattice structures in the unconventional superconductor UPt3 under magnetic field parallel to the hexagonal crystal axis is presented. Only the two-component E2 superconducting state among the other states of different symmetry is proved to be compatible with the recent observations1 of the flux lattice in the A phase misaligned with crystallographic directions. Unlike to the one-dimensional superconductivity where anisotropic interactions caused by non-local electrodynamic corrections are essential for the vortex ordering the formation of slightly distorted triangular flux lattice in UPt3 due to the two-dimensional nature of its superconducting state can be described already in local electrodynamics.2
