WebA mathematical model of magnetic hysteresis loops for weak ac magnetic fields, which is applicable for both symmetrical hysteresis loops that are described by the Rayleigh law of magnetization and asymmetrical loops that are not, has been formulated. The asymmetrical hysteresis loops take place when the ferromagnet is affected, along with an ac … WebJun 4, 1998 · According to its congruency property, the Preisach model demands an equivalent shape of magnetic minor loops, the so‐called Rayleigh loops. We measured … WebFigure 2 shows the hysteresis loops of the two samples at very low applied magnetic field (Rayleigh area). As can be seen, sample A presents a harder magnetic character compared to that of sample B, which indicates that the nanocrystalline character of sample B provokes a more effective intergranular coupling by exchange interaction leading to very soft … dry day means
