Abstract

Landau damping of collective excitations of charge (spin) density in a quasi-2D two-component Fermi system with almost free degenerate and almost localized non-degenerate charge (spin) carriers is proposed as a possible mechanism of quasiparticle relaxation in layered metal-oxide cuprates. The model can explain anomalous temperature dependences of resistivity, Hall constant, electron heat capacity, nuclear spin relaxation rates and paramagnetic susceptibility as well as deviation from the Drude behaviour of high-frequency conductivity.
