We are studying numerically the chaotic dynamics of systems consisting of large systems of interacting classical spins through their Lyapunov spectra and Kolmogorov-Sinai entropy. We are particularly interested in the behaviour of systems with coupling parameters close integrable cases and in the behaviour near phase transitions.
