论文摘要
天空设备的开发需要适当的材料参数调整，以稳定天空并控制其密度。最近已经证明，可以在涉及铁磁铁，铁磁铁和重金属的异质结构的室温下同时稳定不同的天空类型，从而提供了一种新的以天际的编码二进制信息的平台，而不是存在/不存在Skyrmions。在这里，我们通过设计各个层的几何和物质参数来调整此类异质结构中两种天际类型的能量景观。我们发现，铁磁层厚度及其磁各向异性的精细调整使三层系统可以支持一种天空类型或两者的共存，并且具有不同的密度。
The development of skyrmionic devices requires a suitable tuning of material parameters in order to stabilize skyrmions and control their density. It has been demonstrated recently that different skyrmion types can be simultaneously stabilized at room temperature in heterostructures involving ferromagnets, ferrimagnets and heavy metals, offering a new platform of coding binary information in the type of skyrmion instead of the presence/absence of skyrmions. Here, we tune the energy landscape of the two skyrmion types in such heterostructures by engineering the geometrical and material parameters of the individual layers. We find that a fine adjustment of the ferromagnetic layer thickness and thus its magnetic anisotropy, allows the trilayer system to support either one of the skyrmion types or the coexistence of both and with varying densities.
