Mapping Reversal Pathways and Interaction Fields in Artificial Spin Ice
Brindaban Ojha, MatÃas P. Grassi, Vassilios Kapaklis
In artificial spin ice (ASI), magnetic interactions between nanomagnets determine both the stable states and the switching pathways under an applied field. Here, first-order revers…
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…
Magnetic metamaterials by ion-implantation
Christina Vantaraki, Petter Ström, Tuan T. Tran +6
We present a method for the additive fabrication of planar magnetic nanoarrays with minimal surface roughness. Synthesis is accomplished by combining electron-beam lithography, use…
The effect of iron layer thickness on the interlayer exchange coupling in Fe/MgO (001) superlattices
Anna L. Ravensburg, MatÃas 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…
