运用磁力显微镜对硬磁性 Ｎｄ６０Ａｌ１０Ｆｅ２０Ｃｏ１０大块金属玻璃（ＢＭＧ）的磁畴结构进行了研究．结果表明，制备态材料中存在黑白磁斑相邻的微磁结构，磁畴的平均尺度约为３６０ｎｍ．这种磁畴结构与Ｎｄ基ＢＭＧ的硬磁性是紧密相关的．由于ＢＭＧ中存在的短程有序原子团簇的尺度只有几纳米量级，因而磁力图上亚微米尺度的黑白磁斑是由大量的原子团簇在强烈的交换耦合作用下磁矩平行排列形成的．而完全晶化的材料则呈顺磁性，其磁力图上已无明显的磁反差，但仍分布着一些间距较大的平均尺度为９００ｎｍ的低矫顽力铁磁晶态相．
The magnetic domain structure of hard magnetic Nd60Al10Fe20Co10 bulk metallic glass (BMG) was investigated by using a magnetic microscope. The results show that there is a micromagnetic structure adjacent to the black and white magnetic spot in the prepared material, and the average size of the magnetic domains is about 360 nm. This magnetic domain structure is closely related to the hard magnetism of the Nd-based BMG. Because the scale of short-range ordered atomic clusters in BMG is only on the order of nanometers, the black-and-white magnetic patches on the sub-micrometer scale of magnetic maps are formed by parallel arrangement of a large number of atomic clusters with strong magnetic moments under exchanging exchange. However, the completely crystallized material is paramagnetic. There is no obvious magnetic contrast on the magnetic diagram, but some ferromagnetic low-coercive phases with a mean size of 900 nm are still distributed.
