High resolution neutron powder diffraction experiments were carried out on rhombohedral Y{sub 2}Fe{sub 17} and the nitride Y{sub 2}Fe{sub 17}N{sub 3.1} at 10 K. The diffraction data were analyzed by the recently refined Rietveld method. The results o

Iron-rich ternary intermetallics RFe11Ti (R=Ce, Pr and Nd) with a ThMn12-type structure and their nitrides RFe11TiNx (x≈1.5) were carefully prepared. After characterizing them by metallographic and microscopic analyses, we studied structural and ma

YFe 12-x Mo x (x=1 and 3) and full-charged nitrides were prepared. Neutron-ponuder-diffraction experiments were performed at 10 K and room temperature on both the host compounds and their nitrides. The Rietveld technique was used for data analysis. M

Iron-rich ternary intermetallics YFe12−xMox (0.5⩽x⩽4.0) with the ThMn12 tetragonal structure and their nitrides YFe12−xMoxNy(y≈1) were prepared. The lattice parameters increased linearly with Mo concentration (5.06 A3/Mo) The values a = 8.4

In order to clarify the influence of interstitial H and N on the basic magnetism, we carried out X-ray diffraction and magnetic studies of R 2 T 17 hydrides and nitrides with R ≡ Y, Ce or Sm and T ≡ Fe, Co or Ni. The saturation magnetic moment M

Neutron powder diffraction experiments on YFe 12-x Mo x (x = 1 and 3) and fully charged nitrides were performed at 10 K and room temperature. By the Rietveld analysis, we found that the molybdenum atoms mainly occupy the 8i site in the tetragonal ThM

Basic investigations to apply the rapid quenched Nd-Fe-B die-upset technique to fabricate trapezoid-shaped magnets with high energy product were undertaken. Stress around the magnets with indentations during die-upsetting was evaluated by computer si

In order to optimize hot-working conditions of rapidly quenched Nd-Fe-Co-Ga-B magnets, the behavior of plastic deformation at elevated temperatures has been studied. Compressive and tensile tests were performed with various hot-working parameters. Fr
