The upper critical field for the field along the b axis of the orthorhombic ferromagnetic superconductor UCoGe has a particular S shape, akin to the reentrant superconducting phase of URhGe. In order 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.
