dc.description.abstract | The relaxation dynamics of a uniaxial paramagnet of arbitrary spin value S, interacting with a thermal bath,
are treated using the spin-boson model for a particular spin Hamiltonian consisting of the simplest uniaxial
potential in the high temperature, Ohmic damping, and weak spin-bath coupling limits. The signal-to-noise
ratio of the magnetic moment fluctuations in the stochastic resonance of such a paramagnet displays a pronounced
dependence on S for values of S 20. The dependence arises from the quantum spin dynamics which
differs markedly from the magnetization dynamics of classical superparamagnets with S 103?105. | en |
