We proposed the super-ferromagnetism model to analyze the magnetic behavior of a ferromagnetically coupled ferromagnetic cluster system. In the model the magnetic behavior is characterized by two parameters TィイD3intra(/)cィエD3 and TィイD3intrer(/)cィエD3. TィイD3intra(/)cィエD3 represents the Curie temperature of a cluster, that is, the strength of the interaction of magnetic atoms in the cluster. Whereas, TィイD3intrer(/)cィエD3 represents the Curie temperature of the whole system determined by the strength of the interaction between the ferromagnetic clusters.We determined TィイD3intra(/)cィエD3 and TィイD3intrer(/)cィエD3 together with average cluster size in melt-quenched Pr-Fe alloys, in which magnetic clusters are formed by the concentration fluctuation of the amorphous phase in the alloys.The present model can be applied for the analysis of magnetic behavior of inhomogeneous systems. The concept of super-ferromagnetism is closely related to that of cluster-glass, which is used widely but not defined rigorously. The present model has an advantage to give physically well-defined parameters and hence give clear pictures for the magnetic state.
