TRANSPORT-PROPERTIES OF ELECTRON OR HOLE LIQUIDS IN NORMAL-STATE OF HIGH-TC COPPER OXIDES

In earlier work on strongly correlated liquid metals, taken along the liquid-vapour coexistence curve towards the critical point, a relation between a transport property, electrical resistivity, and a thermodyn amic quantity, magnetic susceptibility, has been demonstrated. This sa me type of correlation is pressed here for electron or hole liquids fl owing through antiferromagnetic assemblies in the normal state of some high T(c) copper oxide materials. Elimination of magnetic susceptibil ity in a Fermi liquid framework then leads to the prediction that elec trical resistivity is intimately linked with nuclear spin-lattice rela xation time and empirical data is employed to test this relation. Fina lly, experiments on Hall constant and thermopower are also briefly ref erred to.
