Vortex liquid phase in the p-wave ferromagnetic superconductor UCoGe
arXiv:1803.08468 · doi:10.1103/PhysRevB.98.024517
Abstract
The upper critical field for field along the b-axis of the p-wave ferromagnetic superconductor UCoGe has a particular S-shape, akin to the re-entrant superconducting phase of URhGe. To explore the evolution of the superconducting phase under this transverse magnetic field, we report the thermal conductivity and resistivity measurements, revealing a possible field-induced vortex liquid phase, and supporting a field-induced change of the superconducting order parameter.
