Magnetic Properties of the Ultrafine Co Particle Systems
Journal of Magnetics, Volume 8, Number 1, 31 Mar 2003, Pages 7-12
Abstract
The method for evaluation of the particle size distribution of fine particles from hysteresis loop measurements is Presented. The method is illustrated on the SiO2-based Co nanoparticle systems. The influence of technological conditions of sample preparation onto particle size distribution is investigated.
Keywords: nanoparticle; superparamagnetism; exchange length; particle distribution
