Dependence of the Fe anisotropy on the Dy concentration in the DyxFe6Sn6 (0.3<x<1) compounds

119Sn Mössbauer effect study of DyxFe6Sn6 (x=0.3, 0.5, 1) compounds

“…These short-range interactions in the structure of DyFe 6 Sn 6 , space-group Cmcm, may be described with no significant loss of accuracy using the simpler crystallographic settings of the hexagonal HfFe 6 Sn 6 -type structure [8,[10][11][12]. Therefore for all compounds Sn was considered as equally occupying 3 sites, 2c, 2d and 2e.…”

“…For the title Dy x Fe 6 Sn 6 T ord was attributed to the maxima of ac-susceptibility curves observed at 11 and 5.4 K for x = 1 and 0.5, respectively. For x = 0.3 no evidence of Dy magnetic ordering was found down to 2 K [8].…”

“…least a fraction of μ Fe has been observed [4,8,9]. The fraction of μ Fe which are canted or on the ab-plane may depend on temperature [4,8].…”

“…The remaining two thirds of the Sn atoms lie between antiferromagnetically coupled Fe planes and have zero B transf . In the frame of our investigation on the magnetic properties of A x Fe 6 Sn 6 (x ≤ 1) [5,8,9] we report here the 119 Sn Mössbauer study of Dy x Fe 6 Sn 6 .…”

“…These non-zero B transf are apparently related to the magnetic ordering of Dy. In the frame of our investigation on the magnetic properties of A x Fe 6 Sn 6 (x < 1) [4,8,9] we report here the 119 Sn Mössbauer study of U x Fe 6 Sn 6 . * Corresponding author.…”
