We report on the pressure-induced novel phases of ferromagnetism and superconductivity (SC) in the itinerant ferromagnet UGe2 via the Ge-73-NQR measurements under pressure (P). The NQR spectrum has revealed that the ferromagnetic phases are separated into weakly and strongly polarized phases around a critical value of P-c(*) similar to 1.2 GPa, pointing to a first-order transition around P-c(*). Here we present further evidence for the phase separation into ferromagnetic and paramagnetic phases around a critical pressure P-c similar to 1.6GPa. The measurements of nuclear spin-lattice relaxation rate 1/T-1 have probed that SC sets only in the ferromagnetic phase at T-sc similar to 0.2 K, but it does not in the paramagnetic phase.
