Tuning the metamagnetic transition in the (Co,Fe)MnP system for magnetocaloric purposes
F. Guillou, E. Brueck
The inverse magnetocaloric effect taking place at the antiferro-to-ferromagnetic transition of (Co,Fe)MnP phosphides has been characterized by magnetic and direct ΔTad measurements…
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…
Coupled valence and spin state transition in (Pr0.7Sm0.3)0.7Ca0.3CoO3
F. Guillou, Q. Zhang, Z. Hu +7
The coupled valence and spin state transition (VSST) taking place in (Pr0.7Sm0.3)0.7Ca0.3CoO3 was investigated by soft x-ray absorption spectroscopy (XAS) experiments carried out a…
