Calculating thermal stability and attempt frequency of advanced recording structures without free parameters
Christoph Vogler, Florian Bruckner, Dieter Suess +1
Ensuring a permanent increase of magnetic storage densities is one of the main challenges in magnetic recording. Conventional approaches based on single phase grains are not suitab…
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…
