   The work presents close-form expressions to determine the transient parameters in the case of single exponential processes, and provides an additional constraint which improves the convergence of least-squares methods when applied to multi-exponential transients.

Keywords: thermally activated processes, multi-exponential transients, magnetic disaccommodation, soft magnetic materials
