In recent years, magnetic nano-objects have received a growing attention owing to the development of small-scale fabrication as well as prospects of applications. From magnetically controlled micro-tweezers to radiofrequency oscillators using vortices in nanoparticles [1], a large number of devices which exploit magnetic properties arising on the nanoscale from the competition of different types of energies (exchange, anisotropy, etc.) are envisioned. Research in nanomagnetism focuses on the states resulting from this competition, on their stability and on their possibilities of evolution. Within this field, the research concerning new memory devices is an example where there is a clear technological challenge at hand, but also an opportunity to investigate new physics experimentally.
