铁磁纳米环中的开关机制
Switching Mechanism in Ferromagnetic Nanorings
摘要：
铁磁环表现出许多新颖的物理现象，具有潜在的应用前景。在这里，我们专注于开关过程，这是磁系统的基本特性，对数据存储应用尤其重要。简要介绍了环形几何结构的优点，并对纳米磁性元件的模型和研究方法进行了综述。到目前为止，相关的磁状态确定进行了讨论，特别强调给予涡旋，洋葱，扭曲的状态。这些状态是数据存储应用的潜在候选者。将均匀电场下的开关过程分为三种类型，并详细解释了它们的机理。特别是，从拓扑的角度来看，解释被证明是有启发性的。最后，我们简要讨论了磁性纳米环的圆场开关和数据存储应用。
英文摘要：
Ferromagnetic rings exhibit many novel physical phenomena with promise for potential applications. Here, we focus on switching processes which are fundamental properties of magnetic systems and are especially crucial for data storage applications. A brief introduction on the advantages of ring geometries is presented, followed by a background survey of the model and methods to study nanomagnetic elements. The relevant magnetic states identified until now are discussed, with special emphasis given to vortex, onion, and twisted states. Such states are potential candidates for data storage applications. Switching processes under uniform fields are categorized into three types, and their mechanisms are explained in detail. In particular, explanations from a topological point of view are shown to be enlightening. We conclude with a brief discursion of circular field switching and data storage applications of magnetic nanorings.
