Exponential Dependence of Interlayer Exchange Coupling in Fe/MgO(001) Superlattices on Temperature
Nanny Strandqvist, Tobias Warnatz, Kristbjörg Anna Thórarinsdóttir +3
The interlayer exchange coupling in Fe/MgO(001) superlattices is found to increase exponentially with decreasing temperature. Around 150~K, the field induced response changes from…
Single scan STEM-EMCD in 3-beam orientation using a quadruple aperture
Hasan Ali, Sharath Kumar Manjeshwar Sathyanath, Cheuk-Wai Tai +5
The need to acquire multiple angle-resolved electron energy loss spectra (EELS) is one of the several critical challenges associated with electron magnetic circular dichroism (EMCD…
Texture fluctuations and emergent dynamics in coupled nanomagnets
Samuel D. Slöetjes, Björgvin Hjörvarsson, Vassilios Kapaklis
We analyse the thermal fluctuations of magnetization textures in two stray field coupled elements, forming mesospins. To this end, the energy landscape associated with the thermal…
Thermal excitations within and among mesospins in artificial spin ice
Björn Erik Skovdal, Samuel D. Slöetjes, Merlin Pohlit +3
We provide experimental and numerical evidence for thermal excitations within and among magnetic mesospins, forming artificial spin ice structures. At low temperatures, a decrease…
Emergent tri-criticality in magnetic metamaterials
Björn Erik Skovdal, Gunnar K. Pálsson, P. C. W. Holdsworth +1
Metallic discs engineered on the 100 nm scale have an internal magnetic texture which varies from a fully magnetized state to a vortex state with zero moment. The interplay between…
Influence of misfit strain on the physical properties of Fe thin films
Anna L. Ravensburg, Gunnar K. Pálsson, Merlin Pohlit +2
We investigate the growth of thin Fe layers on MgAlO~(001) and MgO~(001) substrates using dc magnetron sputtering. The crystal quality of Fe layers deposited on MgAlO$_…
