Direct observation of Jahn-Teller critical dynamics at a charge-order Verwey transition
Vinícius Pascotto Gastaldo, Mala N. Rao, Alexey Bosak +10
By means of diffuse and inelastic x-ray scattering (DS,IXS), we probe directly the charge-ordering (CO) dynamics in the Verwey system (NaMn)MnO, where a peculiar qua…
Commensurate structural modulation in the charge- and orbitally-ordered phase of the quadruple perovskite (NaMn)MnO
A. Prodi, A. Daoud-Aladine, F. Gozzo +9
By means of synchrotron x-ray and electron diffraction, we studied the structural changes at the charge order transition =176 K in the mixed-valence quadruple perovskite (N…
Internal-strain mediated coupling between polar Bi and magnetic Mn ions in the defect-free quadruple-perovskite BiMnMnO
A. Gauzzi, G. Rousse, F. Mezzadri +10
By means of neutron powder diffraction, we investigated the effect of the polar Bi ion on the magnetic ordering of the Mn ions in BiMnMnO, the counterp…
Synthesis and Characterization of Single Crystal Samples of Spin- Kagome Lattice Antiferromagnets in the Zn-Paratacamite Family ZnCu(OH)Cl
Tianheng Han, Joel S. Helton, Shaoyan Chu +6
The Zn-paratacamite family, ZnCu(OH)Cl for 0.33, is an ideal system for studying spin-1/2 frustrated magnetism in the form of antiferromagneti…
Pressure-induced Spin-Peierls to Incommensurate Charge-Density-Wave Transition in the Ground State of TiOCl
A. Prodi, J. S. Helton, Yejun Feng +1
The ground state of the spin-Peierls system TiOCl was probed using synchrotron x-ray diffraction on a single-crystal sample at T = 6 K. We tracked the evolution of the structural s…
Searching for Stable Na-ordered Phases in Single Crystal Samples of gamma-NaxCoO2
G. J. Shu, Andrea Prodi, S. Y. Chu +3
We report on the preparation and characterization of single crystal gamma phase NaxCoO2 with 0.25 < x < 0.84 using a non-aqueous electrochemical chronoamperemetry technique. By car…
