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…
Coexistence of distinct skyrmion phases observed in hybrid ferromagnetic/ferrimagnetic multilayers
Andrada-Oana Mandru, Oğuz Yıldırım, Riccardo Tomasello +6
Materials hosting magnetic skyrmions at room temperature could enable new computing architectures as well as compact and energetically efficient magnetic storage such as racetrack…
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…
Hybrid FFT algorithm for fast demagnetization field calculations on non-equidistant magnetic layers
Paul Heistracher, Florian Bruckner, Claas Abert +2
In micromagnetic simulations, the demagnetization field is by far the computationally most expensive field component and often a limiting factor in large multilayer systems. We pre…
GPU Accelerated Atomistic Energy Barrier Calculations of Skyrmion Annihilations
Paul Heistracher, Claas Abert, Florian Bruckner +2
We present GPU accelerated simulations to calculate the annihilation energy of magnetic skyrmions in an atomistic spin model considering dipole-dipole, exchange, uniaxial-anisotrop…
A repulsive skyrmion chain as guiding track for a race track memory
Dieter Suess, Christoph Vogler, Florian Bruckner +1
A skyrmion racetrack design is proposed that allows for thermally stable skyrmions to code information and dynamical pinning sites that move with the applied current. This concept…
