AbstractWe have established the stability and range of the cubic type II phase of Bi1-xWxO1.5+1.5x using a combination of X-ray diffraction, neutron diffraction and X-ray absorption spectroscopy.Type II is a high temperature modification that can be obtained by quenching/rapid cooling of Impedance measurements reveal oxide ionic conductivities comparable to those of yttriastabilised zirconia even after a decrease in ionic conductivity of about half an order of magnitude on thermal cycling due to transition to the tetragonal type Ib phase.

Thermal expansion property of Silver(I)-Oxide (Ag 2 O) was structurally investigated by neutron powder diffraction from 3 K to 400 K, and measured by X-ray powder diffraction from 20 K to 498 K. Temperature dependency of lattice parameter by neutron diffraction indicates the negative thermal expansion (NTE) below room temperature, and it changes to positive thermal expansion (PTE) from 300 K to 400 K. And this result is consistent with X-ray diffraction and TMA measurement. Moreover, the result by X-ray diffraction shows that lattice parameter significantly decreases above 400 K. Since the result by TG measurement shows the mass loss remarkably in this temperature region, it is considered that decreasing lattice parameter above 400 K is caused from thermal decomposition.

Incommensurate Magnetic Structure in the Cubic Noncentrosymmetric Ternary Compound Pr₅Ru₃Al₂

Magnetic susceptibility and neutron powder diffraction experiments have been performed on the noncentrosymmetric ternary compound Pr 5 Ru 3 Al 2 . The previously reported ferromagnetic transition at 24 K was not detected in our improved quality samples. Instead, magnetic ordering was observed in the DC magnetic susceptibility at T N ≃ 3.8 K. Neutron powder diffraction further indicates that an incommensurate magnetic structure is established below T N , with the magnetic modulation vector q ≃ (0.066, 0.066, 0.066) (r.l.u.). A candidate for the magnetic structure is proposed using the representation analysis.Non-colinear incommensurate magnetic structures, such as a helical magnetic structure, have attracted renewed interests because of the recent discovery of novel topological spin textures, for instance magnetic skyrmion [1][2][3][4][5][6] and chiral magnetic soliton lattice. 7-9) A helical magnetic structure is stabilized by the magnetic frustration 10, 11) and/or DzyaloshinskyMoriya (DM) interaction. 12, 13) The latter can be finite for the systems that lack inversion symmetry. It is well known that the DM interaction uniquely selects helicity of the magnetic structure, and hence can give rise to various intriguing topological quantum effects such as the topological Hall effect in the magnetic skyrmion phase. 14) Henceforth, many noncentrosymmetric compounds have been synthesized recently.The ternary compound Pr 5 Ru 3 Al 2 is one of such noncentrosymmetric compounds. 15) It belongs to the noncentrosymmetric and nonmirrorsymmetric cubic I2 1 3 space group. For this symmetry the finite DM interaction is allowed, and hence an incommensurately modulated magnetic structure is expected. Nonetheless, the earlier DC magnetic susceptibility measurement only finds the ferromagnetic transition at 24 K. 15) The lowest temperature of *
