Abstract: type:Journal Article<br />X-ray diffraction and domain observation were performed to evaluate an effect of Nd-rich phase on the c-axis orientation of the Nd–Fe–B melt-spun ribbon. It was found that adequate addition of Nd-rich phase promotes the c-axis orientation of the Nd–Fe–B ribbon. The (Nd2Fe14B1)95(Nd-rich phase)5 ribbon has c-axis orientation in the entire body from bottom to top when melt-spun at wheel speed of 10.0 m/s.
