Newly developed experimental techniques allowed to combine magnetic particles and polymers. These techniques make it possible to create a certain aggregated structures with finely controllable mechanical, magnetic and other properties. Here, we investigate magnetic filaments with different topologies made out of ferromagnetic spherical and ellipsoidal nanoparticles - simple open chains and closed rings which are the ground states of dipolar hard particles (Prokop’eva et al, JETP, 2011; Kantorovich et al, Soft Matter, 2013). Using Langevin dynamics simulations, we analyse different properties of filaments. Thus, we show that shape of particles, the size of their magnetic moment, temperature and filament’s length can significantly change conformation and properties of a single filament. These results will form the basis for developing theoretical models and provide recommendations for the design of novel magnetoresponsive systems.
