A full-fledged micromagnetic code in less than 70 lines of NumPy
Claas Abert, Florian Bruckner, Christoph Vogler +3
We present a complete micromagnetic finite-difference code in less than 70 lines of Python. The code makes largely use of the NumPy library and computes the exchange field by finit…
Fundamental limits in heat assisted magnetic recording and methods to overcome it with exchange spring structures
Dieter Suess, Christoph Vogler, Claas Abert +3
The switching probability of magnetic elements for heat assisted recording is investigated. It is found that FePt elements with a diameter of 5 nm and a height of 10nm show, at a f…
Landau-Lifshitz-Bloch equation for exchange coupled grains
Christoph Vogler, Claas Abert, Florian Bruckner +1
Heat assisted recording is a promising technique to further increase the storage density in hard disks. Multilayer recording grains with graded Curie temperature is discussed to fu…
A three-dimensional spin-diffusion model for micromagnetics
Claas Abert, Michele Ruggeri, Florian Bruckner +4
We implement a finite-element scheme that solves the Landau-Lifshitz-Gilbert equation coupled to a diffusion equation accounting for spin-polarized currents. The latter solves for…
Efficient Energy-minimization in Finite-Difference Micromagnetics: Speeding up Hysteresis Computations
Claas Abert, Gregor Wautischer, Florian Bruckner +2
We implement an efficient energy-minimization algorithm for finite-difference micromagnetics that proofs especially useful for the computation of hysteresis loops. Compared to resu…
Spin-polarized transport in ferromagnetic multilayers: An unconditionally convergent FEM integrator
Claas Abert, Gino Hrkac, Marcus Page +3
We propose and analyze a decoupled time-marching scheme for the coupling of the Landau-Lifshitz-Gilbert equation with a quasilinear diffusion equation for the spin accumulation. Th…
