Figure Caption: Knight shift measurements of PuCoGa5. a NMR spectra of 71Ga in 8 T at a series of temperatures through Tc. The spectra have been offset vertically for clarity. Solid lines are gaussian fits. b The normal-state magnetic shift Ktot of the 59Co and 71Ga(1) versus bulk susceptibility. For intercepts and hyperfine constants see text. Solid lines are fits to the low-temperature data. c The total magnetic shift Ktot of the 59Co and 71Ga(1) versus temperature. For more information see N. J. Curro et al., Nature (London) 434, 622-625 (31 March 2005).
