Evolution of magnetic properties and spin kinetics of cuprates with doping

Abstract

We have shown that properties of lightly doped quasi-layered cuprates can be described on the basis of topological excitation known as skyrmions both thermally excited and induced by quasi-localized electronic holes. We have calculated the average skyrmion radius r 0 and nuclear spin relaxation rate 1/T 1 as a function of temperature and hole concentration. The results are in qualitative agreement with experiments. © Springer Science+Business Media, LLC 2006.
