【 摘 要 】

We study theoretically a cluster of several interacting spins modelling a hypothetical single-molecule magnet. Starting from a spin Hamiltonian, we obtain the individual energy levels and their evolution in an applied magnetic field. By substituting the energy levels into the partition function, we compute macroscopic observables like the magnetisation and the susceptibility of the system.
