Excitation caging in a vertex-frustrated quasiperiodic Einstein artificial spin ice
T. Wang, F. Museur, G. M. Macauley +5
Naturally occurring bulk quasicrystals are rare, and magnetic instances are rarer still, with chemical constraints typically permitting the synthesis of approximants rather than tr…
Current-induced magnetization control in dipolar-coupled nanomagnet pairs and artificial spin ice
A. Pac, G. M. Macauley, J. A. Brock +5
Exploiting current-induced spin-orbit torques (SOTs) to manipulate the magnetic state of dipolar-coupled nanomagnet systems with in-plane magnetic anisotropy, such as artificial sp…
Magnetic-Field Control of Emergent Order in a 3D Dipolar Pyramid Artificial Spin Ice
Luca Berchialla, Gavin M. Macauley, Flavien Museur +2
We realize a three-dimensional artificial spin ice of disconnected nanomagnets interacting solely via dipolar coupling, patterned on square pyramids. This Pyramid artificial spin i…
Realizing Blume-Capel Degrees of Freedom with Toroidal Moments in a Ruby Artificial Spin Ice
Luca Berchialla, Gavin M. Macauley, Flavien Museur +4
Realizing exotic Hamiltonians beyond the Ising model is a key pursuit in experimental statistical physics. One such example is the Blume-Capel model, a three-state spin model, whos…
Ultrafast Laser-Induced Magnetic Relaxation in Artificial Spin Ice Driven by Dipolar Interactions
D. Pecchio, S. Sahoo, O. Chubykalo-Fesenko +6
It is of great interest to develop methods to rapidly and effectively control the magnetic configurations in artificial spin ices, which are arrangements of dipolar coupled nanomag…
Magnetic ordering in out-of-plane artificial spin systems based on the Archimedean lattices
Aleksandra Pac, Gavin M. Macauley, Jamie R. Massey +4
Artificial spin systems, sometimes referred to as artificial spin ices, are arrays of coupled nanoscale magnets that order according to the lattice geometry, nanomagnet shape and m…
Perpendicular-anisotropy artificial spin ice with spontaneous ordering: a platform for neuromorphic computing with flexible timescales
Aleksandr Kurenkov, Jonathan Maes, Aleksandra Pac +4
Arrays of coupled nanomagnets have wide-ranging fundamental and practical applications in artificial spin ices, neuromorphic computing and spintronics. However, lacking in these fi…
Five-stage ordering to a topological-defect-mediated ground state in a buckyball artificial spin ice
Gavin M. Macauley, Luca Berchialla, Peter M. Derlet +1
Artificial spin ices are arrays of coupled nanomagnets, which exhibit a variety of fascinating collective behaviour including emergent magnetic monopoles, charge screening, and nov…
Field-driven Reversal Models in Artificial Spin Ice
Gary W. Paterson, Gavin M. Macauley, Rair Macêdo
We investigate a set of topological arrangements of individual ferromagnetic islands in ideal and disordered artificial spin ice (ASI) arrays in order to evaluate how aspects of th…
Ice-rule made manifold: phase transitions, topological defects and manifold restoration in two-dimensional artificial spin systems
Gavin M. Macauley, Gary W. Paterson, Yue Li +3
Artificial spin ices are arrays of correlated nano-scale magnetic islands that prove an excellent playground in which to study the role of topology in critical phenomena. Here, we…
Heisenberg pseudo-exchange and emergent anisotropies in field-driven pinwheel artificial spin ice
Gary W. Paterson, Gavin M. Macauley, Yue Li +8
Rotating all islands in square artificial spin ice (ASI) uniformly about their centres gives rise to the recently reported pinwheel ASI. At angles around 45, the antif…
