Controlled topological dilution drives cooperative glassy dynamics in artificial spin ice
Davis Crater, Ryan Mueller, Sanjib Thapa +4
It has long been known that disorder, perturbing the energy landscape of magnetic systems, can introduce glassy dynamics. However, the controlled role of increasing disorder in dri…
The dipolar Aleppo lattice: Ground state ordering and ergodic dynamics in the absence of vertex frustration
Gopi Mahato, Davis Crater, Christian Hoyt +7
We introduce the Aleppo spin ice geometry, another variation of decimated square ice patterns, which in contrast to similar systems previously studied, does not exhibit vertex frus…
Plasmon-enhanced optical control of magnetism at the nanoscale via the inverse Faraday effect
Sergii Parchenko, Kevin Hofhuis, Agne Ciuciulkaite +4
The relationship between magnetization and light has been the subject of intensive research for the past century, focusing on the impact of magnetic moments on light polarization.…
Intrinsic chiral field as vector potential of the magnetic current in the zig-zag lattice of magnetic dipoles
Paula Mellado, Kevin Hofhuis, Ignacio Tapia +1
Chiral magnetic insulators manifest novel phases of matter where the sense of rotation of the magnetization is associated with exotic transport phenomena. Effective control of such…
Direct observation of a dynamical glass transition in a nanomagnetic artificial Hopfield network
Michael Saccone, Francesco Caravelli, Kevin Hofhuis +7
Spin glasses, generally defined as disordered systems with randomized competing interactions, are a widely investigated complex system. Theoretical models describing spin glasses a…
Artificial out-of-plane Ising antiferromagnet on the kagome lattice with very small further neighbour couplings
Jeanne Colbois, Kevin Hofhuis, Zhaochu Luo +4
Despite their simple formulation, short range classical antiferromagnetic Ising models on frustrated lattices give rise to exotic phases of matter, in particular due to their macro…
Spin-wave dynamics and symmetry breaking in an artificial spin ice
Susmita Saha, Jingyuan Zhou, Kevin Hofhuis +4
Artificial spin ices are periodic arrangements of interacting nanomagnets successfully used to investigate emergent phenomena in the presence of geometric frustration. Recently, it…
Chiral switching and dynamic barrier reductions in artificial square ice
Naëmi Leo, Matteo Pancaldi, Sabri Koraltan +10
Collective dynamics in lithographically-defined artificial spin ices offer profound insights into emergent correlations and phase transitions of geometrically-frustrated Ising spin…
Balanced Detection in Femtosecond X-ray Absorption Spectroscopy to Reach the Ultimate Sensitivity Limit
W. F. Schlotter, M. Beye, S. Zohar +21
X-ray absorption spectroscopy (XAS) is a powerful and well established technique with sensitivity to elemental and chemical composition. Despite these advantages, its implementatio…
Dependence of energy barrier reduction on collective excitations in square artificial spin ice: A comprehensive comparison of simulation techniques
Sabri Koraltan, Matteo Pancaldi, Naëmi Leo +9
We perform micromagnetic simulations to study the switching barriers in square artificial spin ice systems consisting of elongated single domain magnetic islands arranged on a squa…
Tailoring Vanadium Dioxide Film Orientation using Nanosheets: A Combined Microscopy, Diffraction, Transport and Soft X-ray in Transmission Study
Phu Tran Phong Le, Kevin Hofhuis, Abhi Rana +17
VO2 is a much-discussed material for oxide electronics and neuromorphic computing applications. Here, heteroepitaxy of vanadium dioxide (VO2) was realized on top of oxide nanosheet…
Role of natural convection in the dissolution of sessile droplets
Erik Dietrich, Sander Wildeman, Claas Willem Visser +4
The dissolution process of small (initial (equivalent) radius mm) long-chain alcohol (of various types) sessile droplets in water is studied, disentangling diffusive and…
