What we do
Experiments with magnetic microstructures are expensive and time consuming. We use our own simulation software to predict properties and dynamic behaviour of magnetic systems.
In order to speed up our simulations we develop and implement novel algorithms that are tailored to micromagnetics. Depending on the particular problem we use the finite-element or finite-difference method for spatial discretization.
One of our main interests when investigating magnetic structures is the development and improvement of magnetic sensor. Again we focus on simulations in order to guide the design.
We use 3D printing technology for the development of permanent magnets with spatially varying magnetic properties and complex shapes.
About our group
Micromagnetic simulations are only meaningful if you understand all the bits and pieces starting from ab initio theory up to macroscopic principles like domain theory.
When applying the micromagnetic model you have to be aware of its approximations and limitations. We are interested in pushing the limits of the micromagnetic model by including finite temperature and spin diffusion effects.
When solving the micromagnetic model numerically, it is important to understand the implications of the applied numerical methods. We know the strengths and weaknesses of the different methods like the finite-difference method and the finite-element method and choose the best method for the problem at hand.
We are interested in the complete tool chain from quantum mechanics to macroscopic systems and their experimental realization, see our publication history.
