The effect of inter-particle interaction in samples of Co nanoparticles dispersed in different volume fractions in a wax matrix was 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. These experimental curves do not require AC demagnetized states of the sample, which is an important simplification of the experimental procedure. The results are analyzed with a Generalized Moving Preisach Model.
