| Abstract: | A systematic study of the formation, structure and magnetic properties of (Nd,Dy)3Fe27.5(Ti,Mo)1.5 compounds has been performed. Rietveld analyses of the X-ray patterns of the samples indicate that the concentrations of Ti and Mo affect the formation and structural properties slightly, whereas different rare-earth (Nd and Dy) contents influence them significantly. It is found that high Dy contents make it difficult to form the 3:29-type structures. The Curie temperatures of Nd2.1Dy0.9Fe27.5Ti1.5−xMox decrease monotonically as more Ti was replaced by Mo but their saturation magnetizations remain almost unchanged; in contrast, for Nd3−yDyyFe27.5TiMo0.5, their saturation magnetizations decrease monotonically with increasing Dy contents while their Curie temperatures are constant. |
