Long-range magnetic order and spin-lattice coupling in the delafossite CuFeO2
Volker Eyert, Raymond Fresard, Antoine Maignan
The electronic and magnetic properties of the delafossite CuFeO2 are investigated by means of electronic structure calculations. They are performed using density functional theory…
Magnetic Coupling and Long-Range Order in the Spin-Chain Sulphide Ba2cos3
Andrew D. J. Barnes, Thomas Baikie, Vincent Hardy +4
In this paper, we report on the magnetic properties of Ba2CoS3, a spin-chain compound recently found to be the first Co2+ containing one-dimensional sulphide to show metallic-like…
Anisotropic susceptibility of the geometrically frustrated spin-chain compound Ca3Co2O6
Vincent Hardy, Delphine Flahaut, Raymond Fresard +1
Ca3Co2O6 is a system exhibiting a series of fascinating properties, including magnetization plateaus and remarkably slow dynamics at low-T. These properties are intimately related…
Strongly correlated properties of the thermoelectric cobalt oxide Ca3Co4O9
P. Limelette, V. Hardy, P. Auban-Senzier +7
We have performed both in-plane resistivity, Hall effect and specific heat measurements on the thermoelectric cobalt oxide CaCoO. Four distinct transport regimes…
Large Thermopower in Metallic Oxides: Misfit Cobaltites and Mangano-Ruthenates
Sylvie Hebert, Christine Martin, Antoine Maignan +3
Two different kinds of metal transition oxides have been studied for their large thermopower values. The first one corresponds to the Tl-based misfit cobaltite which is a hole-dope…
