Abstract

Dynamic properties of Co nanoparticle systems were investigated by means of RF transverse susceptibility. To study the effect of interaction between particles, samples of Co nanoparticles dispersed in a wax matrix in different volume fractions were studied. The evolution of interaction intensity in the Co nanoparticle systems as a function of temperature was determined by measuring the Integral Generalized DeltaM curves.
