We report spin-lattice relaxation time measurements in isostructural (HoCoGa type) actinide compounds withdifferent ground states (paramagnet, antiferromagnet and superconductor) using single-crystal samples. The anisotropy oflocal magnetic fluctuation due to coupling on the actinide (magnetic) site is evaluated. In the superconductor PuRhGa, the type magnetic anisotropy is strong compared with non-superconducting compounds. Favorable magnetic anisotropy for -wave superconductivity in -electron systems is discussed.
