Abstract
In single-domain particles magnetic moments behave as overdamped rotary oscillators with a potential ∝ϑ. Thus they make a well-understandable object for studies of stochastic resonance (SR). With a numerically exact approach, we analyze magnetic SR in superparamagnetic assemblies including a situation when an external field creates a controllable inequaliity of the potential-well depths.
