Abstract
Reservoir computing can be implemented in a variety of systems beyond standard CMOS technology. Here, we describe a scheme that relies on a magnetic reservoir consisting of an antidot array, motivated by earlier experiments on ring arrays. We show that antidot lattices can be used as reservoirs much in the same way as ring arrays. We describe geometries in which smaller magnetic fields are needed to induce emergent magnetic patterns in the reservoir, a prerequisite for its use in reservoir computing. High-resolution magnetic imaging of these patterns shows entirely different domains and domain walls, despite the fact that the macroscopic magnetic signal behaves very similarly in both types of reservoirs.
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.
