Creation and Stability of Skyrmion State in Two-Dimensional Magnets at Doping

摘要

It was shown that the hole introduced in CuO2 plane causes the creation of the skyrmion spin configuration. The stability of the skyrmion state is investigated. It was established that the critical values of the exchange interaction anisotropy and interaction between planes at which skyrmion starts to destroy, are much more than in real cuprates.
