“…31,32 Recently neutron-diffraction experiments on ErFe 6 Ge 6 also suggest ferromagnetic Fe sheets, which couple antiferromagnetically across the layer. 33 Because of the large distance between the Fe sheets (у8 Å͒ as compared to 4 Å in ErFe 6 Ge 6 and 2.8 Å for the Mn sheets in YMn 2 Ge 2 , this structure seems unlikely at first view. It is nevertheless appealing as it explains many features.…”

Isothermal section of the Er–Fe–Al ternary system at 800 °C

“…Up to now the Er-Fe-Al ternary system was not studied in the whole concentration range, but some compounds were studied as isostructural members of larger series in order to investigate their physical properties [2][3][4].…”

“…The compound Er 6 Fe 20.3 Al 2.7 was studied as part of the Er 6 Fe 23−x Al x [7] extension into the ternary system. Three single phases in the homogeneity range of ErFe 12−x Al x (ThMn 12 -type) with different stoichiometric compositions, ErFe 7 Al 5 , ErFe 4 Al 8 and ErFe 6 Al 6 have been described on the basis of their crystal structure refinement [2,8,9] and magnetic properties [3,4]. Two phases with different stoichiometric compositions Er 2 Fe 11 Al 6 and Er 2 Fe 13.2 Al 3.8 have been described by Zarechnyuk et al [7] as independent compounds with different types of structure.…”

Crystallographic and magnetic properties of HfFe6Ge6-type REFe6Sn4Ge2 compounds (RE=Y, Gd–Er)

“…Most of the paramagnetic rare earth element compounds crystallize in rather complicated structures resulting from different locations of the RE element in the host CoSn-type sub-structure. Several studies have evidenced some problems regarding the crystallographic ordering of the RE sites and have shown partial disorder depending on the thermal history of the samples [6][7][8][9][10]. The magnetic studies suggested an independent magnetic ordering of the RE and Fe sublattices and, in most of the cases, a non-collinear arrangement of the RE moments with a simultaneous presence of ferro-, antiferro-and/or helimagnetic components [8][9][10][11][12][13][14].…”
