Real-space imaging of confined magnetic skyrmion tubes
M. T. Birch, D. Cortés-Ortuño, L. A. Turnbull +20
Magnetic skyrmions are topologically nontrivial particles with a potential application as information elements in future spintronic device architectures. While they are commonly po…
Improved performance of polycrystalline antiferromagnet/ferromagnet stack by nitrogen assisted deposition
Y. Khaydukov, G. McCafferty, A. Dobrynin +7
The deposition process of the IrMn/CoFe bilayer of antiferromagnet/ferromagnet (AF/FM) type was modified by introducing a nitrogen additive in argon plasma during…
Depth resolved study of annealing in IrMn/(Fe, Co, CoFe) exchange bias systems
Yu. Khaydukov, A. Dobrynin, S. Hassan +7
Depth resolved study of structural and magnetic profiles of antiferromagnetic/ferromagnetic (AFM/FM) system upon annealing was performed in this work. We studied systems comprising…
Stability and Metastability of Skyrmions in Thin Lamellae of CuOSeO
M. N. Wilson, M. T. Birch, A. Å tefanÄiÄ +6
We report small angle X-ray scattering (SAXS) measurements of the skyrmion lattice in two 200~nm thick CuOSeO lamellae aligned with the applied magnetic field parallel to t…
Pinning of Helimagnetic Phase Transitions in Zn-Substituted Skyrmion Host CuOSeO
M. T. Birch, S. H. Moody, M. N. Wilson +9
Magnetic skyrmions are nano-sized topological spin textures stabilized by a delicate balance of magnetic energy terms. The chemical substitution of the underlying crystal structure…
Observation of a temperature dependent asymmetry in the domain structure of a Pd doped FeRh epilayer
C. J. Kinane, M. Loving, M. A. de Vries +10
Using X-ray photoelectron emission microscopy we have observed the coexistence of ferromagnetic and antiferromagnetic phases in a (3 at.%)Pd-doped FeRh epilayer. By quantitatively…
Thermopower and thermal conductivity of superconducting perovskite
S. Y. Li, W. Q. Mo, M. Yu +8
The thermopower and thermal conductivity of superconducting perovskite ( 8 K) have been studied. The thermopower is negative from room temperature to 10 K. C…
Normal state resistivity, upper critical field and Hall effect in superconducting perovskite
S. Y. Li, R. Fan, X. H. Chen +9
The normal state resistivtity, upper critical field and Hall coefficient in superconducting perovskite () have been studied. Above 70 K, $…
Increased lifetime of metastable skyrmions by doping
M. T. Birch, R. Takagi, S. Seki +12
Previous observations of metastable magnetic skyrmions have shown that close to the equilibrium pocket the metastable state has a short lifetime, and therefore rapid cooling is req…
