Abstract
31P nuclear magnetic relaxation has been utilized to study the spin dynamics of U 5f moments in the antiferromagnetic uranium compound UP in the paramagnetic state up to 800 K. The nuclear spin-lattice relaxation time T1 increases almost linearly with temperature above about 300 K. Evaluating the transferred hyperfine coupling constants due to up to the second nearest-neighbor U ions, the relaxation rate l/τf of U 5f moments is deduced. h/τf is found to be comparable to the thermal energy kBT and to increase almost linearly with temperature above about 300 K.
