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.

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.


Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
