This article describes an identification methodology for a Preisach-Neéel model based on a nonlinear Stoner--Wohlfarth energy barrier hypothesis. In the identification, one uses data from a set of remanent curves, the major hysteresis loop at two different temperatures below the blocking temperature and the zero-field-cooled and field-cooled magnetization curves. This identification scheme was experimentally applied to a system of Co ferrite nanoparticles with an average diameter of 3 nm. The quality of the identification procedure is analyzed and the differences between the experimental and computational results are discussed. [ABSTRACT FROM AUTHOR] |
