The nature of the magnetic order in Ca3Co2O6
S. Agrestini, L. C. Chapon, A. Daoud-Aladine +5
We present a detailed powder and single crystal neutron diffraction study of the spin chain compound Ca3Co2O6. Below 25 K, the system orders magnetically with a modulated partially…
Incommensurate magnetic ground state revealed by RXS in the frustrated spin system Ca3Co2O6
S. Agrestini, C. Mazzoli, A. Bombardi +1
We have performed a resonant x-ray scattering study at the Co pre-K edge on a single crystal of Ca3Co2O6. The measurements reveal an abrupt transition to a magnetically ordered sta…
Elliptical hole pockets in the Fermi surfaces of unhydrated and hydrated sodium cobalt oxides
J. Laverock, S. B. Dugdale, J. A. Duffy +9
The surprise discovery of superconductivity below 5K in sodium cobalt oxides when hydrated with water has caught the attention of experimentalists and theorists alike. Most explana…
Magnetization reversal in the orthovanadate RVO3 compounds (R = La, Nd, Sm, Gd, Er and Y): Inhomogeneities caused by defects in the orbital sector of quasi-one-dimensional orbital systems
L D Tung, M R Lees, G Balakrishnan +1
We report on a study of various RVO3 single-crystal samples (R = La, Nd, Sm, Gd, Er and Y) which show temperature-induced magnetization reversal. For compounds with lighter rare-ea…
Investigation of the field-treated magnetic state in Gd5Ge4
S. Majumdar, S. J. Crowe, D. McK. Paul +2
At low temperatures, the intermetallic compound GdGe shows a sharp field-induced transition into a ferromagnetic state around 25 kOe of applied field. The material remains…
