Clocked dynamics in artificial spin ice
Johannes H. Jensen, Anders Strømberg, Ida Breivik +6
Artificial spin ice (ASI) are nanomagnetic metamaterials exhibiting a wide range of emergent properties, which have recently shown promise for neuromorphic computing. However, the…
Observation and formation mechanism of 360° domain wall rings in Synthetic Anti-Ferromagnets with interlayer chiral interactions
Miguel A. Cascales Sandoval, A Hierro-Rodríguez, S. Ruiz-Gómez +10
The Interlayer Dzyaloshinskii-Moriya interaction (IL-DMI) chirally couples spins in different ferromagnetic layers of multilayer heterostructures. So far, samples with IL-DMI have…
Determination of optimal experimental conditions for accurate 3D reconstruction of the magnetization vector via XMCD-PEEM
Miguel A. Cascales Sandoval, A. Hierro-Rodríguez, S. Ruiz-Gómez +10
In this work we present a detailed analysis on the performance of X-ray magnetic circular dichroism photo-emission electron microscopy (XMCD-PEEM) as a tool for vector reconstructi…
Homochiral antiferromagnetic merons, antimerons and bimerons realized in synthetic antiferromagnets
Mona Bhukta, Takaaki Dohi, Venkata Krishna Bharadwaj +7
The ever-growing demand for device miniaturization and energy efficiency in data storage and computing technology has prompted a shift towards antiferromagnetic (AFM) topological s…
Micromagnetics of magnetic chemical modulations in soft-magnetic cylindrical nanowires
L. Álvaro-Gómez, S. Ruiz-Gómez, C. Fernández-González +17
We analyze the micromagnetics of short longitudinal modulations of a high-magnetization material in cylindrical nanowires made of a soft-magnetic material of lower magnetization su…
Size effects in the Verwey transition of nanometer-thick micron-wide magnetite crystals
Adolfo del Campo, Sandra Ruiz-Gómez, Eva M. Trapero +6
We have monitored the Verwey transition in micrometer-wide, nanometer-thick magnetite islands on epitaxial Ru films on Al2O3(0001) using Raman spectroscopy. The islands have been g…
