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 thermodynamic quantity, magnetic susceptibility, has been demonstrated. This same type of correlation is pressed here for electron or hole liquids flowing through antiferromagnetic assemblies in the normal state of some high T(c) copper oxide materials. Elimination of magnetic susceptibility in a Fermi liquid framework then leads to the prediction that electrical resistivity is intimately linked with nuclear spin-lattice relaxation time and empirical data is employed to test this relation. Finally, experiments on Hall constant and thermopower are also briefly referred to.
