Cobalt spin state above the valence and spin-state transition in (Pr0.7Sm0.3)0.7Ca0.3CoO3
F. Guillou, Y. Bréard, V. Hardy
(Pr0.7Sm0.3)0.7Ca0.3CoO3 belongs to a class of cobalt oxides undergoing a first-order transition (T* close to 90 K) associated to a coupled change in the valence and spin-state deg…

Jumps in entropy and magnetic susceptibility at the valence and spin-state transition in a cobalt oxide
V. Hardy, F. Guillou, Y. Bréard
A wide family of cobalt oxides of formulation (Pr,Ln,Ca)CoO3 (Ln being a lanthanide) exhibits a coupled valence and spin-state transition (VSST) at a temperature T*, which involves…

Ordering process and ferroelectricity in a spinel derived from FeV2O4
Q. Zhang, K. Singh, F. Guillou +4
The spinel FeV2O4 is known to exhibit peculiar physical properties, which is generally ascribed to the unusual presence of two cations showing a pronounced interplay between spin,…
