摘要：

A study of the crystallization behaviour correlated with thermomagnetic measurements for Nd8Fe77Co5CuNb3B6 melt-spun ribbons has been carried out. A stable two-phase structure is obtained only for annealing temperatures exceeding 700 degrees C. Furthermore, when the crystallites are sufficiently small to result in significant exchange interactions, the samples reveal an exchange-spring behaviour. (C) 1999 Elsevier Science B.V.
