Magnetic nanoparticles have a wide range of applications, from cancer treatment and data storage to new industrial magnets that can increase the efficiency of generators and electric motors, see e.g. http://spectrum.ieee.org/semiconductors/nanotechnology/the-incredible-pull-of-nanocomposite-magnets. It is expected that new advanced magnetic materials will be built bottom-up using nanoparticles as building blocks.

Using computer simulations, we aim to better understand the link between the structural arrangement of nanoparticles and their collective magnetic properties. To model the magnetic ordering in nanoparticle structures, we code e.g. in Matlab using the molecular dynamics scheme, where Newton’s equations are solved for the magnetic forces that the individual nanoparticle moments are subject to.

In a B.Sc. or M.Sc. project you will work to determine which magnetic structures are stable in different configurations of nanoparticles (e.g. ring-shaped configurations). To do this, your tasks will be to do simulations, hereunder set up the structural arrangement of nanoparticles (e.g. ordered, disordered), then analyze the results in order to quantify and optimize properties.

The project will build upon the material you learned in courses on electromagnetism and solid state physics, introduce you to the concepts in molecular dynamics simulations, and increase your proficiency in programming and materials science.
