magnum.fe: A micromagnetic finite-element simulation code based on FEniCS
Claas Abert, Lukas Exl, Florian Bruckner +2
We have developed a finite-element micromagnetic simulation code based on the FEniCS package called magnum.fe. Here we describe the numerical methods that are applied as well as th…
Numerical Methods for the Stray-Field Calculation: A Comparison of recently developed Algorithms
Claas Abert, Lukas Exl, Gunnar Selke +2
Different numerical approaches for the stray-field calculation in the context of micromagnetic simulations are investigated. We compare finite difference based fast Fourier transfo…
Current- and field-driven magnetic antivortices
Andre Drews, Benjamin Krueger, Markus Bolte +1
Antivortices in ferromagnetic thin-film elements are in-plane magnetization configurations with a core pointing perpendicular to the plane. By using micromagnetic simulations, we f…
Time-Resolved X-ray Microscopy of Spin-Torque-Induced Magnetic Vortex Gyration
Markus Bolte, Guido Meier, Benjamin Krueger +10
Time-resolved X-ray microscopy is used to image the influence of alternating high-density currents on the magnetization dynamics of ferromagnetic vortices. Spin-torque induced vort…
Harmonic oscillator model for current- and field-driven magnetic vortices
Benjamin Krueger, Andre Drews, Markus Bolte +3
In experiments the distinction between spin-torque and Oersted-field driven magnetization dynamics is still an open problem. Here, the gyroscopic motion of current- and field-drive…
