论文摘要
磁性天际是拓扑稳定的准粒子，是能源有效应用的有前途的候选者，例如存储以及逻辑和感应。在这里，我们提出了一个基于Skyrmions的多转弯传感器式式设备的新概念，其中传感旋转的数量是在成核的天空中编码的。与拓扑依赖性动力学结合使用，在设备的限制几何形状中的天空 - 边界力会导致对某些几何形状的自动动力的影响。对于我们的案例，我们用微型模拟和带有连接储层的三角形几何形状中的粗粒硫素方程来描述和研究这种效果，这是传感器表启动设备的一部分。
Magnetic skyrmions are topologically stabilized quasi-particles and are promising candidates for energy-efficient applications, such as storage but also logic and sensing. Here we present a new concept for a multi-turn sensor-counter device based on skyrmions, where the number of sensed rotations is encoded in the number of nucleated skyrmions. The skyrmion-boundary force in the confined geometry of the device in combination with the topology-dependent dynamics leads to the effect of automotion for certain geometries. For our case, we describe and investigate this effect with micromagnetic simulations and the coarse-grained Thiele equation in a triangular geometry with an attached reservoir as part of the sensor-counter device.
