Abstract : We calculate the response of a molecular magnet subject to a time-varying magnetic field and coupled to a heat bath. We propose that observations of calculated oscillations transverse to the field direction may be an effective way of demonstrating quantum tunneling and thus probing the details of level repulsion. The effective model of a triangle of Heisenberg spins and weak anisotropies, as has been used to model the molecular magnets V15 and Cu3, is used to illustrate this.

Keywords : Molecular magnets Out-of-equilibrium dynamics Magnetization curves Hysteresis
