Abstract
We present a simple method for parameterizing the sweep-rate dependence of the coercivity. We use it to fit data obtained from Landau–Lifshitz dynamic simulation, to extrapolate them to experimental time scales. The method is a generalization of the Sharrock theory in which all the data fall on a single universal curve if the coercivity and sweep rate are scaled properly.Keywords
