Finite-size effects in amorphous thin CoZr layers
Vladislav Kurichenko, Parul Rani, Björgvin Hjörvarsson
Profound finite size effects are observed in both the moment and ordering temperature in thin CoZr layers. The results are consistent with the presence of interface r…
Dynamic stabilisation of mesospin chains
Damjan Dagbjartsson, Simon Banks, Björgvin Hjörvarsson
We present a rare example of a one-dimensional system with short-range range interactions for which a self-stabilizing long-range ordered phase persists to finite temperatures. Our…
Quantitative measurement of magnetic dichroic signals at sub-nanometer to atomic scale resolution conditions
Sharath Kumar Manjeshwar Sathyanath, Anna L. Ravensburg, Vassilios Kapaklis +3
When aiming for atomic resolution electron magnetic circular dichroism (EMCD) in STEM mode, the high convergence angle of the electron probe can lead to unforeseen artefacts and st…
Emergent anisotropy in magnetic metamaterials
Nanny Strandqvist, Björn Erik Skovdal, Merlin Pohlit +3
We demonstrate directional dependence of the self-modification of internal mesospin textures in magnetic metamaterials, arising from the coupling of the atomic- and mesoscopic leng…
Multiple energy-scales in vertex-frustrated mesospin systems
Henry Stopfel, Unnar B. Arnalds, Aaron Stein +3
The interplay between topology and energy-hierarchy plays a vital role in the collective magnetic order in artificial ferroic systems. Here we investigate, experimentally, the effe…
The effect of confinement on thermally induced fluctuations in nanomagnets
Samuel D. Slöetjes, Björgvin Hjörvarsson, Vassilios Kapaklis
We study the magnetization dynamics in nanomagnets excited by stochastic magnetic fields to mimic temperature in a micromagnetic framework. The effect of confinement arising from t…
