Abstract
We present a new method to extract the parameters of a log-normal distribut ion of energy barriers in an assembly of ultrafine magnetic particles from simple features of the zero-field cooled and field cooled magnetisation cur ves. The method is established using numerical simulations and is tested on two experimental data sets. (C) 1999 Elsevier Science B.V. All rights rese rved.
