The field dependence of magnetization in superparamagnetic systems can be fitted using a set of Langevin contributions characterized by their particle densities and their magnetic moments. In fact, these contributions are just partial average values over the actual magnetic moment distribution of the system. The achievement of the most adequate mean magnetic moment is non-trivial and depends on the characteristics of the moment distribution and the applied magnetic field range. As an example, results have been applied to a nanocrystalline alloy. |
