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 T_c = 0.7 K. The lack of a coherence peak in 1/T₁ just below T_c, 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.
