Abstract
The nuclear spin-lattice relaxation rates 1 / T1 were found to be independent of temperature in the paramagnetic states of various kinds of metallic magnets. It has been ascertained from quantitative analyses that the values of 1 / T1 in the weak itinerant ferromagnets and the localized moment systems were explained by the SCR and the HBEN theories of spin fluctuations, respectively. Both theories, however, failed to reproduce the experimental results of ferromagnets in the intermediate-regime.
