采用高分辨率扫描电镜和透射电镜研究了标称成分为Nd12.5Fe73Co8B6.5的加氢歧化解吸复合粉体的微观结构。解吸复合阶段各阶段磁畴运动的洛伦兹观察表明，磁畴壁被高矫顽力粉末中富Nd的晶界强烈钉扎。 (C) 2009 年美国物理研究所。 [DOI：10.1063/1.3058671]
The microstructure of hydrogenation disproportionation desorption recombination processed powders with a nominal composition of Nd12.5Fe73Co8B6.5 was investigated by high resolution scanning electron microscopy and transmission electron microscopy. The Lorenz observation of the magnetic domain motion of various stages of the desorption recombination stage indicated that domain walls are strongly pinned by Nd-enriched grain boundaries in high coercivity powder.
