Fast domain walls governed by Årsted fields in cylindrical magnetic nanowires
M. Schöbitz, A. De Riz, S. Martin +14
Since its proposal, the idea to vastly increase data storage density with a magnetic non-volatile 3D shift-register has sustained interest in current-induced domain wall (DW) motio…
Time-resolved imaging of Årsted field induced magnetization dynamics in cylindrical magnetic nanowires
M. Schöbitz, S. Finizio, A. De Riz +7
Recent studies in three dimensional spintronics propose that the Årsted field plays a significant role in cylindrical nanowires. However, there is no direct report of its impact o…
Micromagnetics of magnetic chemical modulations in soft-magnetic cylindrical nanowires
L. Ãlvaro-Gómez, S. Ruiz-Gómez, C. Fernández-González +17
We analyze the micromagnetics of short longitudinal modulations of a high-magnetization material in cylindrical nanowires made of a soft-magnetic material of lower magnetization su…
Quantitative analysis of shadow X-ray Magnetic Circular Dichroism Photo-Emission Electron Microscopy
S. Jamet, S. Da Col, N. Rougemaille +10
Shadow X-ray Magnetic Circular Dichroism Photo-Emission Electron Microscopy (XMCD-PEEM) is a recent technique, in which the photon intensity in the shadow of an object lying on a s…
The interplay of shape and catalyst distribution in the yield of compressible flow microreactors
G. C. Antunes, M. Jiménez-Sánchez, P. Malgaretti +2
We develop a semi-analytical model for transport in structured catalytic microreactors, where both reactant and product are compressible fluids. Making use of the lubrication and F…
Mechanism of current-assisted Bloch-point wall stabilization for ultra fast dynamics
A. De Riz, J. Hurst, M. Schöbitz +5
Two types of domain walls exist in magnetically soft cylindrical nanowires: the transverse-vortex wall (TVW) and the Bloch-point wall (BPW). The latter is expected to prevent the u…
A material view on extrinsic magnetic domain wall pinning in cylindrical CoNi nanowires
M. Schøbitz, O. Novotny, B. Trapp +7
Speed and reliability of magnetic domain wall (DW) motion are key parameters that must be controlled to realize the full potential of DW-based magnetic devices for logic and memory…
Crossover between two different magnetization reversal modes in arrays of iron oxide nanotubes
J. Escrig, J. Bachmann, J. Jing +3
The magnetization reversal in ordered arrays of iron oxide nanotubes of 50 nm outer diameter grown by atomic layer deposition is investigated theoretically as a function of the tub…
