In chiral cubic helimagnets, phases of magnetic skyrmions—topologically protected spin whirls—are stabilized by thermal fluctuations over a narrow region directly below the magnetic ordering temperature T_c. Due to often being touted for use in applications, there is a high demand to identify new ways to stabilize equilibrium skyrmion phases far below T_c where they may display an enhanced robustness against external perturbation due to a larger magnetic order parameter. Here, from quantum beam experiments on the chiral magnet Co₇Zn₇Mn₆, we unveil a direct correlation between the stability of its second skyrmion phase-stable far from T_c, and a concomitant enhancement of an underlying magnetic fluctuation rate that is driven by geometric magnetic frustration. The influences of other leading skyrmion stability mechanisms, such as those derived from thermal fluctuations and low T cubic anisotropies, are shown to be weak in this system. We therefore advance the existence of a fundamental mechanism for stabilizing topological skyrmions in Co₇Zn₇Mn₆ chiral magnet that draws upon magnetic frustration as the key ingredient.

在手性立方六面体中，通过天空上下正好位于磁有序温度T _c以下的狭窄区域内的热涨落，可以稳定磁天文离子的相（在拓扑上受保护的自旋涡旋）。由于经常被吹捧用于应用中，因此迫切需要找到新的方法来稳定远低于T _c的平衡天生离子相，在这些新方法中，由于较大的磁阶参数，它们可能表现出增强的抵抗外部干扰的鲁棒性。在这里，通过对手性磁体Co ₇ Zn ₇ Mn ₆进行的量子束实验，我们揭示了远离T _c的第二个天sky离子相稳定的稳定性之间的直接相关性。，以及随之而来的由几何磁性受挫感驱动的潜在磁性波动率的增强。在该系统中，其他领先的天胶稳定机制的影响（例如由热涨落和低T立方各向异性引起的影响）显示出微弱的影响。因此，我们提出了一种以磁化挫折为主要成分的稳定Co ₇ Zn ₇ Mn ₆手性磁体中的拓扑天空离子的基本机制的存在。
