Magnetic Skyrmion as a Nonlinear Resistive Element: A Potential Building Block for Reservoir Computing
Open accessAbstract
The topologically protected magnetic textures called skyrmions may provide a suitable basis for $r\phantom{\rule{0}{0ex}}e\phantom{\rule{0}{0ex}}s\phantom{\rule{0}{0ex}}e\phantom{\rule{0}{0ex}}r\phantom{\rule{0}{0ex}}v\phantom{\rule{0}{0ex}}o\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}r$ $c\phantom{\rule{0}{0ex}}o\phantom{\rule{0}{0ex}}m\phantom{\rule{0}{0ex}}p\phantom{\rule{0}{0ex}}u\phantom{\rule{0}{0ex}}t\phantom{\rule{0}{0ex}}i\phantom{\rule{0}{0ex}}n\phantom{\rule{0}{0ex}}g$, one approach to brain-inspired cognitive computing. Reservoirs of self-organized skyrmions offer potential advantages in size, efficiency, and complexity, compared to systems of memristive devices, quantum-dot lasers, and atomic switches. The basic element here is an isolated skyrmion in a ferromagnetic ribbon; thus the authors examine current flow through magnetic skyrmions based on anisotropic magnetoresistance, analyzing the nonlinear current-voltage characteristics. The scheme they provide offers a path to spintronic neuromorphic computing.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
