The structural features of magnetically anisotropic SmCo[sub 5] ribbons prepared by melt spinning have been investigated by means of transmission electron microscopy. It was determined that this kind of SmCo[sub 5] ribbons are made up of structural domains, which consist of layered grains regularly packed along the c-axis direction. The c axes of the grains generally lie in the ribbon plane and along the length. The SmCo[sub 5] grains are well crystallized in the conventional hexagonal structure (P6/mmm). The properties of grain boundaries either with or without impurity phases have been systematically analyzed. © 2002 American Institute of Physics.
