Beyond conventional skyrmions in synthetic antiferromagnets
Kayla Fallon, Reshma Peremadathil-Pradeep, Christopher E. A. Barker +14
Magnetic skyrmions are topologically protected spin textures that can act as reconfigurable nanoscale information carriers. In synthetic antiferromagnets (SAFs), interlayer exchang…
Spin wave resonance in yttrium iron garnet stripe domains
Daniel Prestwood, Chris E. A. Barker, Kilian D. Stenning +15
We study a thin film yttrium iron garnet sample that exhibits magnetic stripe domains due to a small perpendicular magnetic anisotropy. Using wide-field magneto-optic Kerr effect m…
Thermoelectric Fingerprinting of Bloch- and Néel-type Skyrmions
Christopher E. A. Barker, Elias Saugar, Katharina Zeissler +6
Magnetic skyrmions are nanoscale spin textures that exhibit topological stability, which, along with novel thermal and electrical transport properties, make them the ideal candidat…
Skyrmion motion in a synthetic antiferromagnet driven by asymmetric spin wave emission
Christopher E. A. Barker, Charles Parton-Barr, Christopher H. Marrows +2
Skyrmions have been proposed as new information carriers in racetrack memory devices. To realise such devices, a small size; high speed of propagation; and minimal skyrmion Hall an…
