Abstract

We use the example of the cuboctahedron, a highly frustrated molecule with 12 sites, to study the approach to the classical limit. We compute magnetic susceptibility, specific heat, and magnetic cooling rate at high magnetic fields and low temperatures for different spin quantum numbers s. Remarkably big deviations of these quantities from their classical counterparts are observed even for values of s which are usually considered to be almost classical. © 2009 IOP Publishing Ltd.
