Abstract :
A systematic study of the phase formation in the iron-rich end of the Dy-Fe-V ternary system has been carried out using combination of X-ray diffraction (XRD), thermogravimetric analysis (TGA) and 57 Fe Mossbauer spectroscopy. A new Dy3(Fe0.927V0.073)29. compound has been identified, which crystallizes in the monoclinic Nd 3(Fe1-xTix)29 (x=1.24) structure with lattice parameters of a=10.605(8) Å, b=8.475(7) Å, c=9.672(7) Å and β=97.06(4)°. The Curie temperature is 478±3 K. The average 57Fe hyperfine field is 20.9(2) T at 293 K, which corresponds to an average Fe magnetic moment of about 1.49 μB
