Description

Within the t-J model, the unusual spin response in the electron doped antiferromagnets on a triangular lattice has been discussed. The spin-lattice relaxation rate divided by temperature, 1/(T1T), shows a V-shape behavior in the temperature range 0.05 J < T < 0.7 J, which reflects the strong antiferromagnetic spin fluctuation within the CoO2 plane, and is in qualitative agreement with experimental observation on the electron doped cobaltates
