Regular and Chaotic Dynamics of Classical Spin Systems
In the context of the present discussion of the nature of quantum chaos /1/, the dynamics of spin clusters has been the subject of several investigations /2–6/ recently. The interest is focussed on the characteristic properties of quantum spin systems whose classical counterparts are nonintegrable. As a basis for the investigation of regular and chaotic spin motion, we have examined the problem of integrability of classical spin clusters /7, 8/.
