    • According to J. Kikuchi
    • According to J. Kikuchi and M. Itoh, inhomogeneous relaxation is observed below 9-10 K in CuGeO3, which undergoes a spin-Peierls transition at 14 K. They fitted the recovery curve to the double-exponential function. Double-exponential analysis can separate the intrinsic relaxation rate from the extrinsic one. In the case of EtMe3 P [Pd (dmit) 2] 2, unfortunately, the recovery curve follows the stretched-exponential function rather than the double-exponential one, and thus we cannot extract the intrinsic relaxation rate.

    • We observe a very slight decrease in the NMR intensity at 3.5 kbar below about 10 K in Fig. 3. We cannot assess whether the decrease is reliable or within experimental error. Even if it is intrinsic, the volume fraction of the metallic phase is extremely low.

    • The data at 4.8 kbar tend to have slightly smaller values of β than the data at 6.0 and 8.0 kbar. Although we cannot conclude whether this is reliable or within experimental error, an extremely low volume of the insulating phase possibly exists at 4.8 kbar.
