Evidence for hard and soft substructures in thermoelectric SnSe
S. R. Popuri, M. Pollet, R. Decourt +2
SnSe is a topical thermoelectric material with a low thermal conductivity which is linked to its unique crystal structure. We use low-temperature heat capacity measurements to demo…
Glass-like thermal conductivity in SrTiO3 thermoelectrics induced by A-site vacancies
S. R. Popuri, A. J. M. Scott, R. A. Downie +5
The introduction of A-site vacancies in SrTiO3 results in a glass-like thermal conductivity while Nb substituted samples maintains good electrical conductivity. This unexpected res…
Experimental evidence for an intermediate phase in the multiferroic YMnO3
G. Nénert, M. Pollet, S. Marinel +3
We have studied YMnO by high-temperature synchrotron X-ray powder diffraction, and have carried out differential thermal analysis and dilatometry on a single crystal sample.…
Iodine intercalation in Bi/Ca/Co/O layered cobaltites

Non-linear electrical response in a charge/orbital ordered CaMnO crystal : the charge density wave analogy
A. Wahl, S. Mercone, A. Pautrat +2
Non-linear conduction in a charge-ordered manganese oxide PrCaMnO is reported. To interpret such a feature, it is usually proposed that a breakdown of the cha…
Anomaly in the dielectric response at the charge orbital ordering transition of crystalline Pr0.67Ca0.33MnO3
Silvana Mercone, Alexandre Wahl, Alain Pautrat +2
The complex impedance of a Pr0.67Ca0.33MnO3 crystal has been measured. The frequency dependence is studied for a wide range of temperatures (50K-403K) and is found to be characteri…
