在我們的实验工作中,观察了Alnico V合金在不同磁性状态下的粉紋图。样品为8×8×15毫米的长方体。結果表明,从1300℃淬火的試样,畴結构具有通常的单軸晶体的180°Weiss畴的特征(图1)。估計它的磁晶各向异性常数与鈷单晶为同一数量級,粉紋图与鈷单晶的相类似(图2)。 In our experimental work, we observed the graininess of Alnico V alloy in different magnetic states. Samples were 8 × 8 × 15 mm cuboids. The results show that the domain structure has the characteristics of a normal uniaxial 180 ° Weiss domain from a sample quenched at 1300 ° C (Fig. 1). It is estimated that its magnetocrystalline anisotropy constant and cobalt single crystal is the same order of magnitude, pink and cobalt single crystal similar (Figure 2).
