Synthesis and structure of the scandium‐rich indides Sc₅Ni₂In₄ and Sc₅Rh₂In₄

Magnetic Properties of Ho5Ni2In4

“…In this structure the Ho atoms occupy three different sublattices: Ho1 2a site: 0, 0, 0; Ho2 and Ho3 4g site: x, y, 0 with different values of the x and y parameters, Ni atoms occupy 4h site: x, y, 1/2 and In atoms form two sublattices In1 and In2 both at 4h site: x, y, 1/2 but with different values of x and y parameters. The determined crystal structure parameters are collected in Table. These parameters agree well with the published data [1,4,5]. The additional peaks of the small intensities connected with HoNiIn and Ho 2 Ni 2−x In phases are observed.…”

“…Only for RNiIn magnetic measurements were performed indicating that this compound is ferromagnet [3]. The R 5 Ni 2 In 4 compounds with a large concentration of the rare-earth element exist for R = Dy-Tm and Lu, Y [4,5] and crystallize in an orthorhombic crystal structure of the Lu 5 Ni 2 In 4 -type [6].…”

Crystal structure of the RE11Ni4In9 compounds (RE = La, Ce, Pr, Nd, Sm, Gd, Tb and Y)

“…Dy, Ho, Er, Tm, Lu [8,9] and Sc [10] while the larger rare earths La-Nd, Sm, Gd, Tb, Y form the structure of the Nd 11 Pd 4 In 9 type [18]. The variation of the parameter (V/N) (where V is the volume of the unit cell, N -the number of atoms per unit cell) for RE 11 Ni 4 In 9 and RE 5 Ni 2 In 4 [4,9] compounds as a size function of the effective ionic radii of the rareearths (R 3þ , coordination number VI) [24] is shown in Fig.…”

“…Now we continue systematic investigation of the RE-T-In (RErare-earths, T -transition metals) systems and their compounds. In the systems RE-Ni-In (RE ¼ Dy, Ho, Er, Tm, Lu, Sc) there are compounds with the Lu 5 Ni 2 In 4 structure type [8][9][10]. The compounds with the same structure type are also formed in the some systems RE-{Rh, Ir, Pd, Pt}-In [10][11][12][13][14][15] and {Zr, Hf}-{Rh, Ir}-In [16,17].…”

Recently, [18,19] we have been investigating the crystal structure of Nd 11 Pd 4 In 9 which is related to the Lu 5 Ni 2 In 4 crystal structure.…”
