Starting from the observation that at very low temperatures an isolated nanomagnet can be treated as an effective two-state system, we introduce a model to study quantum tunnelling and decoherence phenomena. We assume that the total spin of the magnet interacts with a spin bath. We show that depending upon the interaction strengths the molecule can exhibit tunnelling with or without decoherence. We also investigate the case where the spin-spin interaction is mediated by phonons.
