Magnetic and transport properties of Yb5T4Ge10 (T=Co, Rh, Ir)

Crystal Structure and Properties of Yb5Ni4Ge10

“…The large Ge-Ge distances were observed in Yb 5 T 4 Ge 10 (T = Co, Rh, Ir) compounds as well. [12] The interlayer Ni-Ge distances [2.3397(4) Å] are shorter and stronger than the intralayer Ni-Ge distance [2.4308(3) Å and 2.3806(3) Å], and all Ni-Ge distances are shorter than the sum of the covalent radii of 2.77 Å [33] which indicates strong Ni-Ge interactions. The Ni-Ge interlayer distances are comparable to 2.327 Å in YbNiGe 2 , [29] and the Ni-Ge intralayer distances are comparable to 2.428 Å in YbNiGe, [24] 2.404 Å in YbNi 2 Ge 2 , [24] and 2.421 Å Yb 3 Ni 11 Ge 4 .…”

“…[10,11] So far, several ytterbium compounds, Yb 5 T 4 X 10 (T = Co, Rh, Ir and X = Si, Ge) within the Sc 5 Co 4 Si 10 type structure have been reported. [12,13] Magnetic and transport studies on Yb 5 T 4 Ge 10 (T = Co, Rh, Ir) show that they are paramagnetic metals. [12] Coexistence of magnetic ordering (antiferromagnetic at 50 K) and a charge density wave was observed in Yb 5 Ir 4 Si 10 .…”

Degeneracy Dpendence of the Kadowaki–Woods Relation in Heavy-Fermion Systems

“…Recently, a number of new Yb-based compounds are discovered. [34][35][36][37] Progress of the theory is quite an important theme.…”

Direct observation of remarkable crystalline-electric-field effect in quasi-two-dimensional antiferromagnet Er5Ir4Si10 single crystal by low-temperature specific heat

“…The attractive phenomena in this ternary compound are antiferromagnetic phase transition [1][2][3][4][5][6][7], superconducting phase transition [1,[8][9][10][11][12][13][14][15], charge-density wave phase transition [16][17][18][19][20][21][22][23][24][25][26][27][28][29] and the nuclear magnetism [7]. This compound group crystallizes in the tetragonal Sc 5 Co 4 Si 10 -type crystal structure and the space group * Corresponding author.…”
