The Impact of Local Strain Fields in Non-Collinear Antiferromagnetic Films
Freya Johnson, Frederic Rendell-Bhatti, Bryan D. Esser +5
Antiferromagnets hosting structural or magnetic order that breaks time reversal symmetry are of increasing interest for 'beyond von Neumann computing' applications because the topo…
Complementary ADF-STEM: a Flexible Approach to Quantitative 4D-STEM
Bryan D Esser, Joanne Etheridge
Scanning transmission electron microscopy (STEM) has a broad range of applications in materials characterization, including real-space imaging, spectroscopy, and diffraction, at le…
The anomalous Hall effect in non-collinear antiferromagnetic MnNiN thin films
David Boldrin, Ilias Samathrakis, Jan Zemen +7
We have studied the anomalous Hall effect (AHE) in strained thin films of the frustrated antiferromagnet MnNiN. The AHE does not follow the conventional relationships with ma…
Chiral Bobbers and Skyrmions in Epitaxial FeGe/Si(111) Films
Adam S. Ahmed, James Rowland, Bryan D. Esser +4
We report experimental and theoretical evidence for the formation of chiral bobbers - an interfacial topological spin texture - in FeGe films grown by molecular beam epitaxy (MBE).…
Molecular Beam Epitaxy Growth of [CrGe/MnGe/FeGe] Superlattices: Toward Artificial B20 Skyrmion Materials with Tunable Interactions
Adam S. Ahmed, Bryan D. Esser, James Rowland +2
Skyrmions are localized magnetic spin textures whose stability has been shown theoretically to depend on material parameters including bulk Dresselhaus spin orbit coupling (SOC), i…
Robust Zero-Field Skyrmion Formation in FeGe Epitaxial Thin Films
J. C. Gallagher, K. Y. Meng, J. T. Brangham +4
B20 phase magnetic materials, such as FeGe, have been of significant interests in recent years because they enable magnetic skyrmions, which can potentially lead to low energy cost…
