Anisotropic spin fluctuations and superconductivity in "115" heavy fermion compounds; $$^{59}$$Co NMR study in PuCoGa$$_5$$

Baek, S.-H.*; Sakai, Hironori  ; Bauer, E. D.*; Mitchell, J. N.*; Kennison, J. A.*; Ronning, F.*; Thompson, J. D.*

We report results of $$^{59}$$Co nuclear magnetic resonance measurements on a single crystal of superconducting PuCoGa$$_5$$ in its normal state. The nuclear spin-lattice relaxation rates and the Knight shifts as a function of temperature reveal an anisotropy of spin fluctuations with finite wave vector ${it q}$. By comparison with the isostructural members, we conclude that antiferromagnetic ${it XY}$-type anisotropy of spin fluctuations plays an important role in mediating superconductivity in these heavy fermion materials.
