Abstract

We report 73Ge-NMR/NQR measurements on the itinerant ferromagnetic (FM) superconductor UGe2 at P= 1.2GPa. The temperature (T) dependence of the nuclear spin lattice relaxation rate (1/T1) at zero field has demonstrated the onset of the superconducting (SC) transition at Tc = 0.7 K. The lack of a coherence peak in 1/T1 just below Tc, followed by a T3-like behavior, provide compelling evidence for the unconventional nature of the SC state that coexists with the FM state on a microscopic scale in UGe2.
