Abstract

We study the nuclear relaxation rate 1∕T1 as a function of temperature for a superconducting ferromagnetic coexistent system using a p-wave triplet model for the superconducting pairing symmetry. This calculation is contrasted with a singlet s-wave previously studied. We see for the s-wave case that there is a Hebel-Slichter peak, albeit reduced due to the magnetization, and no peak for the p-wave case. We then compare these results to a nuclear relaxation rate experiment on UGe2 to determine the possible pairing symmetry signatures in that material. It is seen that the experimental data are inconclusive to rule out the possibility of s-wave pairing in UGe2.
