Abstract��The first��order reversal curve (FORC) diagrams is regarded as a topic of interest in both physics and geology, and scientists take this method as "fingerprint" of hysteresis. For hysteresis system, FORC diagram have been used for characterization of interactions between particles and coercivity distribution etc, and lead to a detailed understand of kinetic effects in processes of magnetization, e.g. varied rate of applied magnetic filed. FORC diagrams can also be used in ferroelectric, thermal and elastic hysteresis systems. The method of FORC diagram in magnetic systems is introduced by comparing with Preisach models. The process of gaining FORC diagram by using Takacs model is validated. The application of FORC diagrams in nanocrystalline composite magnetic materials is offered.��
