Research Abstract |
We have theoretically studied the high field and low temperature superconducting phase of the heavy fermion superconductor CeCoIn5 and have pointed out the presence of FFLO and antiferromagnetic orders, both of which are novel effects induced by the paramagnetic pair-breaking, in the above-mentioned novel phase. Satisfactory results consistent with experimental observations have been obtained. Further, we have considered a possibility of a FFLO-like spatially modulated superconducting state in a d-wave superconducting film in zero field and argued that stability of this state against the magnetic field results in an intriguing magnetic phase diagram which may be verified in an experimental under a natural set up.
