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 |
