Thermal activation in permanent magnets
Simon Bance, Johann Fischbacher, Alexander Kovacs +3
The coercive field of permanent magnets decays with temperature. At non-zero temperature the system can overcome a finite energy barrier through thermal fluctuations. Using finite…
Numerical optimization of writer geometries for bit patterned magnetic recording
A. Kovacs, H. Oezelt, S. Bance +6
A fully-automated pole-tip shape optimization tool, involving write head geometry construction, meshing, micromagnetic simulation and evaluation, is presented. Optimizations have b…
LaBonte's method revisited: An effective steepest descent method for micromagnetic energy minimization
Lukas Exl, Simon Bance, Franz Reichel +3
We present a steepest descent energy minimization scheme for micromagnetics. The method searches on a curve that lies on the sphere which keeps the magnitude of the magnetization v…
Guided self-assembly of magnetic beads for biomedical applications
Markus Gusenbauer, Ha Nguyen, Franz Reichel +7
Micromagnetic beads are widely used in biomedical applications for cell separation, drug delivery, and hypothermia cancer treatment. Here we propose to use self-organized magnetic…
Simulation of magnetic active polymers for versatile microfluidic devices
Markus Gusenbauer, Harald Özelt, Johann Fischbacher +7
We propose to use a compound of magnetic nanoparticles (20-100 nm) embedded in a flexible polymer (Polydimethylsiloxane PDMS) to filter circulating tumor cells (CTCs). The analysis…
A tunable cancer cell filter using magnetic beads: cellular and fluid dynamic simulations
Markus Gusenbauer, Ivan Cimrak, Simon Bance +4
In the field of biomedicine magnetic beads are used for drug delivery and to treat hyperthermia. Here we propose to use self-organized bead structures to isolate circulating tumor…
Self-organizing magnetic beads for biomedical applications
Markus Gusenbauer, Alexander Kovacs, Franz Reichel +4
In the field of biomedicine magnetic beads are used for drug delivery and to treat hyperthermia. Here we propose to use self-organized bead structures to isolate circulating tumor…
Fast stray field computation on tensor grids
Lukas Exl, Winfried Auzinger, Simon Bance +3
A direct integration algorithm is described to compute the magnetostatic field and energy for given magnetization distributions on not necessarily uniform tensor grids. We use an a…
