“…1 would only contribute to reciprocal lattice wave vectors. Magnetic ordering observed in this compound gives satellites at (h±τ ,0,0) with τ = 0.115 as reported near each reciprocal lattice wave vectors 40 . This value appears as the average of Ch(1), Ch(2) and Ch(4) in Table II but the zone center is at 1/2 in reciprocal space and not near a structural reciprocal lattice wave vector.…”

A phenomenological model accounts for the calculation of incommensurate ordering wave vectors (IC) in several Ce-and U-based f-electron itinerant compounds (CePtSn, CePdSn, CeNiSn, CeRhIn5, URu2Si2, CeNiAsO, CeCu (6−x) Aux, UNi2Al3, CeCuSn) as well as in BSSCO, Rb2ZnBr4, MnSi and prototypical IC system Chromium metal. This model is justified by a many-body topological one-dimensional (1-D) Dirac Hamiltonian after center of mass transformation on a chiral set of momenta defined by a local expansion of crystallographic Bragg planes. Implications for the emergence of long range bulk states driven by fluctuations with this model are discussed.

“…CeCuSn has most intensively been investigated [8][9][10][11][12][13][14][15][16][17][18][19][20][21]. But the structure of CeCuSn has so far only been investigated on the basis of powder diffraction data, i.e.…”

“…Magnetic, resistivity and specific heat studies on single-crystal and polycrystalline CeCuSn exhibits complex magnetic ordering in this compound [11][12]20]. Sakurai et al observed antiferromagnetic ordering (T N ) around 8 K in arc-melted CeCuSn, which also exhibited weak spontaneous magnetization.…”

“…A recent single-crystal neutron diffraction experiment shows that the onset of antiferromagnetic ordering occurs around 12 K and an inflection around 8 K is seen in the temperature dependence of the magnetic intensities. The magnetic ground state is characterized by a magnetic wave vector k = (0.115, 0, 0) [20]. CeCuSn has repeatedly been studied in order to understand the ground-state properties [19].…”

Two modifications of CeCuSn were prepared from the elements: the high-temperature (β ) modification crystallizes directly from the quenched sample, while the low-temperature (α) modification is formed after annealing at 700 • C for one month. Both modifications were investigated by powder and single crystal X-ray diffraction. We find for β -CeCuSn the ZrBeSi-type structure, space group P6 3 /mmc, a = 458.2(1), c = 793.7(2) pm, wR2 = 0.0727, 148 F 2 values, 8 variable parameters. In the case of α-CeCuSn we find the NdPtSb-type structure, space group P6 3 mc, a = 458.4(1), c = 785.8(2) pm, wR2 = 0.0764, 233 F 2 values, 11 variable parameters. The copper and tin atoms build up layers of ordered [Cu 3 Sn 3 ] hexagons. The layers are planar in β -CeCuSn, however, with highly anisotropic displacements of the copper and tin atoms. In α-CeCuSn a puckering effect is observed resulting in a decrease of the c lattice parameter. Both modifications of CeCuSn exhibit antiferromagnetic ordering, but there is a considerable difference in their magnetic behaviour. Anomalies in the physical properties of the α-and β -modifications of CeCuSn have been detected by Mössbauer spectroscopy and magnetic and specific heat measurements, which serve to explain the structure-property relations.
