摘要：

We outline the method for evaluation of the particle size distribution of the magnetic nanoparticles from the hysteresis loop measurements. We apply the method to study the ultrafine Co particles filling the porous silica gel matrix (SiO2). The influence of the technological conditions of the sample preparation onto particle size distribution function is demonstrated. (C) 2003 Elsevier B.V. All rights reserved.
