Description
Magnetic filaments constitute a novel type of supramolecular polymers at the scale of tenths of nanometers that can have permanent magnetic properties at room temperatures in contrast with chemical 1D polymers which are magnetic only at T < 100K. Magnetic filaments have an enourmous potential for new applications in nanothechnology at the same time that pose an interesting case of research for Soft Matter community due to the non-isotropic character of the magnetic interaction. The idea of magnetic filaments is not new at all, nature has been using systems very similar to the magnetic filaments since the Cretaceous in magnetostatic bacterias. Nonetheless, humankind has just recently begun to caress its potential for novel applications. Numerical simulations can largely help to unravel and understand the behaviour of such magnetic systems as well as assess the usefulness of the magnetic filaments for new technologies. In this talk we will present our recent advances in the characterization of magnetic filaments through numerical simulations, which includes the study of the phase behaviour of such systems in bulk as well as near an interacting surface.
