5. 2 dependence of the resistivity has been reported in the normal state of organic layered superconductors: e.g. L. N. Bulaevskii: Adv. Phys. 37 (1988) 443. However, neither the Wilson ratio nor Kadowaki-Woods ratio (described below) seems to be in accord with the universalities for strongly correlated systems.
