Mössbauer study of HfFe2 and Hf0.75Ta0.25Fe2

Original language description

Mossbauer spectrum measured on ferromagnetic HfFe2 at 296 K, consists of four six-line components and one doublet. The Laves phase HfFe2 has three kinds of crystal structures: cubic MgCu2C15, hexagonal MgZn2C14 and MgNi2C36. We assigned two sextets to the 2a and 6h sites of C14, one to the C15 and the fourth sextet to the minor presence of alpha-Fe. The doublet originates from small amount of FeO, apparently a corrosion product. The pseudobinary compound of Hf0.75Ta0.25Fe2 C14 undergoes the first - order transition to antiferromagnetic (AFM) state at about 180 K due to the strong spin fluctuation. Therefore, a magnetic sextet and a doublet were observed for the spectra assigned to the 6h and 2a site. The second sextet is attached to the minor presenceof Fe3O4.
