Анотація

A theoretic analysis of magnon-induced damping Г of quasiparticle states in the normal phase of doped copper-oxide high-Tc materials is developed, based on a microscopic model which accounts for the specific 2D structure of their electron and magnon spectra. Among the obtained energy and temperature dependences of Г in different regimes, the most peculiar is the anomalously early onset of linear temperature dependence ГµT with a doping-independent coefficient.
