Abstract

We investigate reentrant superconductivity in an Ising ferromagnetic superconductor URhGe under a transverse magnetic field hx. The superconducting transition temperature for p-wave order parameters Tsc is calculated and shows two domes as a function of hx. We find strong enhancement of Tsc in the high-field dome near a saturation field hs where the spins align in the transverse direction. Soft magnons generate strong attractive interactions there. Spin components of the pairing show a significant change between hx<hs and hx>hs. We also discuss the appearance of superconductivity with zero-spin pair due to cancellation between external and exchange fields.
