Nuclear Magnetic Relaxation in Nearly Ferromagnetic YCo₂

抄録

The Knight shift, K, and the nuclear spin-lattice relaxation time, T₁, of ⁵⁹Co have been measured in an exchange-enhanced Pauli paramagnet YCo₂. 1⁄(T₁T)_d has been found to be proportional to χ_d, which is in good accord with the prediction from the self-consistent renormalization (SCR) theory of spin fluctuations in weakly or nearly ferromagnetic metals.
