In the low disorder phase, the saturation loop displays a discontinuity that is reflected by a nonvanishing magnetization m‘ after a series of nested loops. In this case, at low fields the loops are not symmetric and the Rayleigh law does not hold.

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 …
