Size and profile of skyrmions in skyrmion crystals

Abstract Size is a fundamental quantity of magnetic skyrmions. A skyrmion can be local circular object and in an isolated form. also coexist with group its siblings condensed phase. Each phase takes stripe shape at low density high density. Skyrmions form crystal (SkX). So far, size SkX has not been seriously studied. Here, by using generic chiral film, it found that different parameter dependence as those for skyrmions stripes. formula good spin profile SkXs are proposed. These findings have important implications searching stable smaller the room temperature.
