Magnetoelastic properties and stability of hollow nanocomposites — •Markus E. Gruner, Sanjeev K. Nayak, and Peter Entel — Institute of Physics, Universität Duisburg-Essen, Campus Duisburg, D-47048 Duisburg

We investigate the magnetic and elastic properties of hollow spherical nanocomposite systems using the Hybrid Monte Carlo method. The nanocomposites consist of ferromagnetic nanoparticles with a diameter of 14 nm, which are arranged densely packed on the surface of a sphere. The magnetic coupling is described by dipolar interactions, whereas the elastic properties are given by pair potentials. We consider especially the stability and deformation of the systems under the influence of a magnetic field and external pressure.
