Description
We examine the nuclear spin-lattice relaxation rates 1/T1 of PuRhGa5 and PuCoGa5, in particular, in normal state. PuRhGa5 exhibits a gradual suppression of (T1T)-1 below 25K far above Tc∼8.5K, while measurements for PuCoGa5 reveal a monotonic increase down to Tc. We propose that this behavior is consistently understood by the crossover from the two-dimensional quantum antiferromagnetic regime of the local 5f-electron spins of Pu to the concomitant formation of the fermion pseudogap based on the two-component spin-fermion model
