| Abstract: | We report 69Ga NMR measurements on the itinerant compound UFeGa5 using a single crystal sample. Hyperfine coupling constants at both the Ga(1) and Ga(2) sites are determined for H∥a and c-axes based on Knight shift versus susceptibility plots. The T-dependence of the spin-lattice relaxation time (T1) has been determined at both sites for H∥a and c-axes. From these quantities, the magnetic fluctuations are estimated for both axes. The complex nature of the hyperfine interactions is discussed. |
