Flexoelectricity and Flexomagnetism
Alexander Edström, Massimiliano Stengel
Strain gradients, unlike homogeneous strain, are odd under space inversion and unlock couplings that are strictly forbidden in the parent crystal. At the nanoscale, and in curved l…
Design of 2D Skyrmionic Metamaterial Through Controlled Assembly
Qichen Xu, Zhuanglin Shen, Alexander Edström +7
Despite extensive research on magnetic skyrmions and antiskyrmions, a significant challenge remains in crafting nontrivial high-order skyrmionic textures with varying, or even tail…
Simulations of magnetic Bragg scattering in transmission electron microscopy
Justyn Snarski-Adamski, Alexander Edström, Paul Zeiger +4
We have simulated the magnetic Bragg scattering in transmission electron microscopy in two antiferromagnetic compounds, NiO and LaMnAsO. This weak magnetic phenomenon was experimen…
Curved Magnetism in CrI
Alexander Edström, Danila Amoroso, Silvia Picozzi +2
Curved magnets attract considerable interest for their unusually rich phase diagram, often encompassing exotic (e.g., topological or chiral) spin states. Micromagnetic simulations…
Atomically sharp domain walls in an antiferromagnet
Filip Krizek, Sonka Reimers, Zdeněk Kašpar +18
The interest in understanding scaling limits of magnetic textures such as domain walls spans the entire field of magnetism from its relativistic quantum fundamentals to application…
Magnetic anisotropy in Permalloy: hidden quantum mechanical features
Debora C M Rodrigues, Angela B Klautau, Alexander Edström +5
By means of relativistic, first principles calculations, we investigate the microscopic origin of the vanishingly low magnetic anisotropy of Permalloy, here proposed to be intrinsi…
Magnetic Effects in the Paraxial Regime of Elastic Electron Scattering
Alexander Edström, Axel Lubk, Ján Rusz
Based on a recent claim [Phys. Rev. Lett. 116, 127203 (2016)] that electron vortex can be used to image magnetism at the nanoscale in elastic scattering experiments, using transmis…
Magnetic properties of FeSiB and its alloys with P, S, and Co
Mirosław Werwiński, Sofia Kontos, Klas Gunnarsson +7
FeSiB has been synthesized and magnetic measurements have been carried out, revealing that M = 0.92 MA/m at T = 300 K. The M vs T curve shows a broad peak ar…
Enhanced and Tunable Spin-Orbit Coupling in Tetragonally Strained Fe-Co-B Films
Ruslan Salikhov, Ludwig Reichel, Benjamin Zingsem +8
We have synthesized 20 nm thick films of tetragonally strained interstitial Fe-Co-B alloys epitaxially grown on Au55Cu45 buffer layer. The strained axis is perpendicular to the fil…
Elastic scattering of electron vortex beams in magnetic matter
Alexander Edström, Axel Lubk, Ján Rusz
Elastic scattering of electron vortex beams on magnetic materials leads to a weak magnetic contrast due to Zeeman interaction of orbital angular momentum of the beam with magnetic…
Magnetic properties of (FeCo)B alloys and the effect of doping by 5 elements
A. Edström, M. Werwiński, Diana Iuşan +12
We have explored, computationally and experimentally, the magnetic properties of \fecob{} alloys. Calculations provide a good agreement with experiment in terms of the saturation m…
Electronic structure and magnetic properties of L1_0 binary alloys
Alexander Edström, Jonathan Chico, Adam Jakobsson +2
We present a systematic study of the magnetic properties of L1 binary alloys FeNi, CoNi, MnAl and MnGa via two different density functional theory approaches. Our calculations…
