Preparation and properties of nanostructured magnetic hollow microspheres: experiment and simulation

This article presents the experimental realization of magnetic hollow microspheres. Starting from core–shell microspheres with an organic core and a shell composed of nanoparticles, we remove the core using a plasma etching technique. An estimate of the magneto-elastic effects arising from the interplay of magnetic dipolar interactions and cohesive energy, which can be expected in such structures, is given with the help of computer simulations using the hybrid Monte Carlo method.
