Mapping Reversal Pathways and Interaction Fields in Artificial Spin Ice
Brindaban Ojha, Matías 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…
Probing deuterium-induced magnetic phase transitions in TbCo alloys with in-situ polarized neutron reflectometry
Robbie G. Hunt, Gunnar K. Pálsson, Matías P. Grassi +3
Hydrogen-based magneto-ionics is a promising approach for rapid magnetoelectric control of spintronic devices. Most investigations so far into the magneto-ionic manipulation of rar…
Long-Range Magnetic Order in Structurally Embedded Mesospin Metamaterials
Christina Vantaraki, Oier Bikondoa, Matías P. Grassi +11
Engineered assemblies of interacting magnetic elements-magnetic metamaterials-provide a powerful route to tailor collective magnetic order and dynamics. By structuring matter at th…
Magnetic texture control in ion-implanted metamaterials
Christina Vantaraki, Kristina Ignatova, Dmitrii Moldarev +5
We study experimentally the impact of the additive fabrication method on the magnetic properties of Fe-implanted Pd square artificial spin ice lattices. Our findings show that…
Control of Ferrimagnetic Compensation and Perpendicular Anisotropy in TbCo with H ion implantation
Robbie G. Hunt, Dmitrii Moldarev, Matías P. Grassi +2
The tuning of magnetic properties through electrochemical loading of hydrogen has recently attracted significant interest as a way to manipulate magnetic devices with electric fiel…
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…
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…
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…
