Abstract
Magnetic skyrmions are topological spin swirls possessing intriguing electromagnetic properties. The integration of skyrmion materials into flexible substrates has led to the development of flexible spintronics with high performance. However, research into flexible skyrmion materials remains limited. Here, we report the growth of [Pt/Co/Ta]10 multilayer, a typical system hosting skyrmions, on multiple flexible substrates. By combining atomic force microscopy with magnetization measurements, we establish a correlation between surface morphology and perpendicular magnetic anisotropy. The field-driven evolution of skyrmions is also discussed. Additionally, to explain the observed differences in magnetic domain structures of samples grown on flexible substrates and Si substrates, the relationship between magnetic domain width and the variations in magnetic parameters is investigated. Our findings reveal that skyrmion materials can be grown on diverse flexible substrates and tuned by substrate morphology, which shows promising prospects for wearable flexible spintronic devices.
期刊介绍:
Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology.
In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics.
APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field.
Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
