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…
