论文摘要

众所周知,在设计操作Skyrmion Racetrack内存时面临的几个挑战。在这些挑战中,如果研究人员仅依靠金属材料,可以确定一些矛盾。因此,将对氧化物材料扩展到氧化物材料中对于弥合矛盾的间隙至关重要。在这篇局部综述中,我们首先简要修改了稳定和操纵Skymions涉及的理论和标准,然后研究偶极稳定的磁性气泡的行为。接下来,我们将探索具有磁电耦合的多效性天际效果,到目前为止,只能在Cu $ _2 $ _2 $ _3 $中稳定,以及在某些极性材料中稀有的散装Néel-Néel-type Skyrmions。作为插曲部分,我们在经历了氧化物薄膜的最新进展之前,回顾了异常(AHE)和拓扑厅效应(The)的理论。还讨论了有关替代解释的辩论。最后,这篇综述以未来的前景结束,即使用界面电荷转移的有前途的策略和(111) - 钙钛矿的方向使Skyrmion Research领域受益。

Several challenges in designing an operational Skyrmion racetrack memory are well-known. Among those challenges, a few contradictions can be identified if researchers were to rely only on metallic materials. Hence, expanding the exploration on Skyrmion Physics into oxide materials is essential to bridge the contradicting gap. In this topical review, we first briefly revise the theories and criteria involved in stabilizing and manipulating Skymions, followed by studying the behaviors of dipolar-stabilized magnetic bubbles. Next, we explore the properties of multiferroic Skyrmions with magnetoelectric coupling, which can only be stabilized in Cu$_2$OSeO$_3$ thus far, as well as the rare bulk Néel-type Skyrmions in some polar materials. As an interlude section, we review the theory of Anomalous (AHE) and Topological Hall Effect (THE), before going through the recent progress of THE in oxide thin films. The debate about an alternative interpretation is also discussed. Finally, this review ends with future outlooks about the promising strategies of using interfacial charge-transfer and (111)-orientation of perovskites to benefit the field of Skyrmion research.
