Abstract

The Knight shift and the nuclear spin-lattice relaxation rate, 1/ T 1 , of 59 Co in LuCo 2 have been measured. 1/ T 1 T due to the d-electron spins was found to be proportional to the d-spin susceptibility in good agreement with the SCR theory. From the quantitative analysis, the characteristic temperature, T 0 , implying the energy width of the dynaical spin-fluctuation spectrum is estimated for LuCo 2 together with those for the typical nearly ferromagnetic metals. The value T 0 may be related to the degree of the ferromagnetic tendency as welll as the temperature of χ maximum in the nearly itinerant ferromagnet.
