N2 - We report spin-lattice relaxation time measurements in isostructural (HoCo Ga5 -type) actinide compounds with different ground states (paramagnet, antiferromagnet, and superconductor) using single-crystal samples. The anisotropy of local magnetic fluctuations due to LS coupling on the actinide (magnetic) site is evaluated. In the superconductor PuRh Ga5, the XY -type magnetic anisotropy is strong compared with nonsuperconducting compounds. Favorable magnetic anisotropy for d -wave superconductivity in f -electron systems is discussed.
