The modulated magnetic structure of Ho5Sb3

The magnetic structure of the compound Ho5Sb3

“…In 100 Oe, the ZFC magnetization shows a broad plateau region between 60 and 12 K, similar to that reported in Ref. [11]. Below 12 K, the magnetization drops precipitously.…”

“…Our results show that Ho 5 Sb 3 orders magnetically close to 60 K. Neutron diffraction patterns at various temperatures reveal details about the temperature dependent alignment of the magnetic moments which is at variance with the model reported previously in Ref. [11].…”

“…: conical for Tb 5 Sb 3 [3], Tb 5 Si 3 [4] and Dy 5 Si 3 [5], flat spiral for Tb 5 Ge 3 [6], amplitude sine modulated structure for Dy 5 Sb 3 [7] and collinear for Er 5 Si 3 [8], sine modulated collinear antiferromagnetic in Er 5 Ge 3 [9]. The magnetic properties and magnetic structure of Ho 5 Sb 3 have earlier been reported in the literature [10,11]. From the thermal variation of the magnetization taken in an applied field of 1 kOe, it was inferred that Ho 5 Sb 3 orders magnetically at 30 K, lower than the paramagnetic Curie temperature of 86 K [10].…”

“…From the thermal variation of the magnetization taken in an applied field of 1 kOe, it was inferred that Ho 5 Sb 3 orders magnetically at 30 K, lower than the paramagnetic Curie temperature of 86 K [10]. The nature of the magnetic order was investigated later by neutron diffraction recorded at 293 and 4.2 K [11]. The authors in Ref.…”

“…The authors in Ref. [11] concluded that Ho 5 Sb 3 orders antiferromagnetically at 30 K and shows an incommensurate magnetic structure with a propagation wave vector K ¼ [0.288, 0, 0] reciprocal lattice unit. The mean magnetic moment of the Ho atoms at two sites, 4d and 6g, was found to have a value of 8.65 m B inclined at an angle of 491 to the (0 0 1), c-axis.…”
