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…
Using Thermodynamics and Microstructure to Mitigate Overfitting in Pellet Reduction Models
Ömer K. Büyükuslu, Fabrice Yang, Dierk Raabe +2
Direct reduction of iron using hydrogen-rich gas is rapidly emerging as a key strategy for green steel production. This process involves complex, multiscale phenomena, encompassing…
Boundary-induced phase in epitaxial iron layers
Anna L. Ravensburg, Mirosław Werwiński, Justyna Rychły-Gruszecka +9
We report the discovery of a boundary-induced body-centered tetragonal (bct) iron phase in thin films deposited on MgAlO () substrates. We present evidence for thi…
Terahertz emission from -W/CoFe epitaxial spintronic emitters
Venkatesh Mottamchetty, Rimantas Brucas, Anna L. Ravensburg +8
We report efficient terahertz (THz) generation in epitaxial -W/CoFe spintronic emitters. Two types of emitters have been investigated; epitaxial -W/Co$_{…
The effect of iron layer thickness on the interlayer exchange coupling in Fe/MgO (001) superlattices
Anna L. Ravensburg, Matías P. Grassi, Björgvin Hjövarsson +1
We describe the effect of the Fe layer thickness on the antiferromagnetic interlayer exchange coupling in [Fe/MgO] superlattices. An increase in coupling strength with increasi…
GenL: An extensible fitting program for Laue oscillations and whole pattern fitting
Anna L. Ravensburg, Johan Bylin, Vassilios Kapaklis +1
GenL is a flexible program that can be used to simulate and/or fit X-ray reflectivity and X-ray diffraction data from epitaxial thin films exhibiting, for example, Laue oscillation…
Epitaxy enhancement in oxide/tungsten heterostructures by harnessing the interface adhesion
Anna L. Ravensburg, Rimantas Brucas, Denis Music +4
The conditions whereby epitaxy is achieved are commonly believed to be mostly governed by misfit strain. We report on a systematic investigation of growth and interface structure o…
Influence of misfit strain on the physical properties of Fe thin films
Anna L. Ravensburg, Gunnar K. Pálsson, Merlin Pohlit +2
We investigate the growth of thin Fe layers on MgAlO~(001) and MgO~(001) substrates using dc magnetron sputtering. The crystal quality of Fe layers deposited on MgAlO$_…
Enhanced THz emission from spintronic Fe/Pt emitters through crystal growth optimization
Agne Ciuciulkaite, Oliver Gueckstock, Anna Ravensburg +6
We investigate the THz emission characteristics of ferromagnetic/non-magnetic metallic heterostructures, focusing on thin Fe/Pt bilayers. In particular, we report on the impact of…
