Among those challenges, a few contradictions can be identified if researchers are to rely only on metallic materials. Hence, expanding the exploration of 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 skyrmions, 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 Cu2OSeO3 thus far, as well as the rare bulk Néel-type skyrmions in some polar materials. As an interlude section, we review the theory of the anomalous 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 a future outlook regarding the promising strategies of using interfacial charge transfer and (111)-orientation of perovskites to benefit the field of skyrmion research. | Source Title: | Journal of Physics D: Applied Physics | URI: | https://scholarbank.nus.edu.sg/handle/10635/189001 | ISSN: | 13616463 | DOI: | 10.1088/1361-6463/abc03f |
