Only a few elements are ferromagnetic and the most common are iron, cobalt and nickel. These elements satisfy a condition, called the Stoner criterion, which determines whether materials are ferromagnetic. Recently, a different class of ferromagnetic materials based on alternating ultrathin layers of carbon-60 (C60, also called Buckminster-fullerenes or Buckyballs) and non-magnetic metals (e.g. copper or Cu), have exhibited the signatures of ferromagnetism. This development may lead to entirely new ways of understanding magnetic ordering and use of magnetic materials in information technology. The magnetism is associated with the number of interfaces of C60 and Cu, and key issue in understanding the origin of this unusual ferromagnetism is how the ferromagnetism decays away from the interfaces. Neutron scattering is the ideal tool to answer this intriguing question.
