Abstract

We present a new method to extract the parameters of a log-normal distribution of energy barriers in an assembly of ultrafine magnetic particles from simple featurees of the zero-field cooled and field cooled magnetisation curves. The method is established using numerical simulations and is tested on two experimental data sets.
