Antiferromagnetic ordering in the novel Dy3Ge4 and DyGe1.3 compounds studied by neutron diffraction and magnetic measurements

Structural chemistry and physical properties of the rare earth silicide Dy3Si4

“…The structure was found to be isotypic with the Ho 3 Si 4 type [8]. Similar or derivative structures were proposed for polycrystalline binaries, namely Tb 2 Si 3−δ [9], R 3 Si 4 (R = Pr, Nd, Yb) [10][11][12], and R 3 Ge 4 (R = Dy, Ho, Er, Y) [13][14][15][16], characterized by X-ray powder or neutron diffraction techniques. Eu 3 Si 4 was also found to crystallize in space group Immm with the europium atoms adopting a divalent ground state [17].…”

Isothermal section of the Al–Dy–Ge ternary system at 673K

“…However, the compound Dy 3 Ge 4 in this system reported in Ref. [35] was observed under our experimental conditions. The XRD patterns of the samples No.…”

Magnetocaloric effect in the binary intermetallic compound DySi

“…The DySi 2 compound of GdSi 2 -type structure is reported to be antiferromagnetic with a Nee´l temperature of 17 K or 10 K [13,14], the signature of which is not at all discernible in the ac and dc magnetization data of the DySi compound under study. The isostructural DyGe 1.33 compound of the AlB 2 structure also has its antiferromagnetic ordering temperature $16 K [15], and hence lack of any anomaly in the low-field magnetization data of the DySi compound confirms that the 7 wt% AlB 2 -type parasitic phase has negligible effects on the bulk magnetic properties.…”
