Webous high disorder phase, where at low field the loops are described by the Rayleigh law. 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 … Webthe Rayleigh loops of over a hundred basaltic specimens. The most important phenomenon Results observed was that quite a good number of rocks We have studied the magnetic behaviour of showed constricted Rayleigh loops. different kinds of basalts and dolerites, „ numbering over a hundred, in fields of 1 to 10 Oe WebRayleigh loops may arise in other ways, e.g., from large multidomain (MD) grains, the loops in that case should have BHC /A values in the range 0.03 to 0.1 (Néel, 1955), where A and B are the Rayleigh constants and Hc is the bulk coercivity; such loops are too narrow to be ob- north central kansas air downs kansas
