Abstract :
This paper presents a method to separate the reversible and irreversible parts of magnetization in real ferromagnetic systems. The basic hypothesis is that the first-order reversal curve (FORC) diagram includes effects of both the reversible and irreversible components while the remanent second-order reversal curve (SORCR) diagram includes essentially only the irreversible component. This means that the difference of the two diagrams describes only the reversible part. The experimental and simulated results were compared and the differences are discussed. Various scalar Preisach-type models have been used to simulate the FORC, SORCR and the difference between the two distributions.
