论文摘要
在数值上研究了中心对称的正交晶格系统中磁性天际晶体的稳定性。通过在单轴过扭曲的三角形晶格上使用动量分辨的相互作用进行有效的自旋模型进行模拟退火，我们发现，当在动量空间中由双重$ Q $结构组成时，Skyrmion晶体可以强大地实现。此外，我们表明，通过调谐依赖键相关的各向异性交换相互作用的符号来获得具有相反气息数的抗型天空晶体，该符号源自相对论的自旋轨道耦合。
The stability of a magnetic skyrmion crystal in a centrosymmetric orthorhombic lattice system is numerically investigated. By performing the simulated annealing for an effective spin model with the momentum-resolved interaction on a uniaxially distorted triangular lattice, we find that the skyrmion crystal is robustly realized when dominant interaction channels consist of the double-$Q$ structure in momentum space. Moreover, we show that an anti-type skyrmion crystal with the opposite skyrmion number is obtained by tuning the sign of the bond-dependent anisotropic exchange interaction that originates from the relativistic spin-orbit coupling.
