On the strong impact of doping in the triangular antiferromagnet CuCrO2
Antoine Maignan, Christine Martin, Raymond Fresard +5
Electronic band structure calculations using the augmented spherical wave method have been performed for CuCrO2. For this antiferromagnetic (T_N = 24 K) semiconductor crystallizing…
Electronic structure and thermoelectric properties of CuRh(1-x)MgxO2
Antoine Maignan, Volker Eyert, Christine Martin +3
Electronic structure calculations using the augmented spherical wave method have been performed for CuRhO2. For this semiconductor crystallizing in the delafossite structure, it is…
Magnetic field dependence of the magnetic phase separation in Pr1-xCaxMnO3 manganites studied by small-angle neutron scattering
Damien Saurel, Annie Brulet, Andre Heinemann +3
Transport properties of manganese oxides suggest that their colossal magnetoresistance (CMR) is due to percolation between ferromagnetic metallic (FM) clusters in an antiferromagne…
Non-linear effects and Joule heating in I-V curves in manganites
Silvana Mercone, Raymond Fresard, Vincent Caignaert +6
We study the influence of the Joule effect on the non-linear behavior of the transport I-V curves in polycrystalline samples of the manganite Pr0.8Ca0.2MnO3 by using the crystallin…
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…
