Abstract
In single-domain particles magnetic moments behave as overdamped rotar y oscillators with a potential proportional to cos(2) theta. Thus they make a well-understandable object for studies of stochastic resonance (SR). With a numerically exact approach, we analyze magnetic SR in su perparamagnetic assemblies including a situation when an external fiel d creates a controllable inequality of the potential-well depths.
