We introduce a new class of isolated three-dimensional skyrmion that can occur within the cone phase of chiral magnetic materials. These novel solitonic states consist of an axisymmetric core separated from the host phase by an asymmetric shell. These skyrmions attract one another. We derive regular solutions for isolated skyrmions arising in the cone phase of cubic helimagnets and investigate their bound states.
我们引入了一类新的孤立三维斯格明子，它可以出现在手性磁性材料的锥相中。这些新型孤子态由一个轴对称核心和一个非对称壳层组成，该壳层将核心与主体相分隔开来。这些斯格明子相互吸引。我们推导了立方螺旋磁体锥相中孤立斯格明子的正则解，并研究了它们的束缚态。
