Phase co-existence and structured diffuse scattering seen by X-ray 3D mapping of reciprocal space for Cs0.8Fe1.6Se2
A. Bosak, V. Svitlyk, A. Krzton-Maziopa +6
AxFe2-ySe2 (A=K, Rb, Cs) superconductors may show a complex mixture of structural phases even in a single crystal form. A full sphere of the diffraction intensity has been collecte…
The effect of compressive strain on the Raman modes of the dry and hydrated BaCe0.8Y0.2O3 proton conductor
Qianli Chen, Tzu-Wen Huang, Maria Baldini +7
The BaCe0.8Y0.2O3-δ proton conductor under hydration and under compressive strain has been analyzed with high pressure Raman spectroscopy and high pressure x-ray diffraction. The p…
Spiral magnetic structure in spin-5/2 frustrated trimerized chains in SrMn3P4O14
Masashi Hase, Vladimir Yu. Pomjakushin, Lukas Keller +7
We study a spin-5/2 antiferromagnetic trimerized chain substance SrMn3P4O14 using neutron powder diffraction experiments. The coplanar spiral magnetic structure appears below T_N1…
Negative magnetization of Li2Ni2Mo3O12 having a spin system composed of distorted honeycomb lattices and linear chains
Masashi Hase, Vladimir Yu. Pomjakushin, Vadim Sikolenko +4
We study themagnetism of a spin-1 substance Li2Ni2Mo3O12. The spin system consists of distorted honeycomb lattices and linear chains of Ni2+ spins. Li+ ions enter about 25% and 50%…
Direct observation of local Mn-Mn distances in the paramagnetic compound CsMnxMg1-xBr3
A. Furrer, Th. Strässle, J. P. Embs +4
We introduce a novel method for local structure determination with a spatial resolution of the order of 0.01 Angstroem. It can be applied to materials containing clusters of exchan…
Structural Evolution of One-dimensional Spin Ladder Compounds Sr14-xCaxCu24O41 with Ca doping and Related Hole Redistribution Evidence
Guochu Deng, Vladimir Pomjakushin, Václav Petříček +3
Incommensurate crystal structures of spin ladder series Sr14-xCaxCu24O41 (x=3, 7, 11, 12.2) were characterized by powder neutron scattering method and refined using the superspace…
