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…
Magnetic Order and Long-Range Interactions in Mesoscopic Ising Chains
Christina Vantaraki, Matías P. Grassi, Kristina Ignatova +4
We investigate the design of magnetic ordering in one-dimensional mesoscopic magnetic Ising chains by modulating long-range interactions. These interactions are affected by geometr…
Demagnetization dynamics after noncollinear dual optical excitation
Sergii Parchenko, Matthias Riepp, Simon Marotzke +4
We explore the impact of optical excitation using two interfering ultrashort optical pulses on ultrafast magnetization dynamics. Our investigation focuses on Pt/Co/Pt multilayers a…
One-shot pair distribution functions of thin films using lab-based x-ray sources
Johan Bylin, Vassilios Kapaklis, Gunnar K. Pálsson
We demonstrate the feasibility of obtaining accurate pair distribution functions of thin amorphous films down to 80 nm, using modern laboratory-based x-ray sources. The pair distri…
Modelling nanomagnet vertex dynamics through Coulomb charges
Samuel D. Slöetjes, Matías P. Grassi, Vassilios Kapaklis
We investigate the magnetization dynamics in nanomagnet vertices often found in artificial spin ices. Our analysis involves creating a simplified model that depicts edge magnetizat…
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…
