摘要：

From the temperature dependences of the 59Co Knight shift and the nuclear spin-lattice relaxation rate in the exchange-enhanced paramagnetic metal CoSe2, it is shown that the amplitudes of the temperature-dependent spin density fluctuations are saturated at T* = 130 K. This fact indicates that there exist local moment type fluctuations above T*. The results obtained from the present NMR investigation are in general accord with the predictions based on the general theory of spin fluctuations in itinerant electron systems developed recently by Moriya and Takahashi. © 1979.
