45Sc NMR and 55Mn NQR have been measured in Y1-xScxMn2 down to 0.3 K. The temperature dependence of the nuclear spin-lattice relaxation rates, 1 / T1, for 45Sc is well interpreted within the scheme of the self-consistent renormalization (SCR) theory for nearly antiferromagnetic metals in spite of relatively large amplitude of Mn spin fluctuations.
