Description

We report a systematic study of the crystallographic and magnetic structures of the RFe11.5Ta0.5 (R ≡ Lu, Er, Ho, Dy and Tb) compounds carried out by means of neutron powder diffraction. Thermal dependencies of lattice parameters, magnetic moments and magnetization directions have been determined. The hierarchy of the Fe magnetic moments at the 8i, 8j and 8f sites was found to be μ8i>μ8j≥μ8f for all compounds at all temperatures. The influence of the atomic environments on the strength of the Fe local moments at each of the crystallographic sites is discussed. The results of the magnetic refinement are compared to those previously obtained from magnetic measurements on the same compounds. (author)
