Misfit-layered cobaltite with an anisotropic giant magnetoresistance: Ca 3 Co 4 O 9
A.C. Masset,Claude Michel,A. Maignan,M. Hervieu,Olivier Toulemonde,F. Studer,B. Raveau,Jiri Hejtmanek +7 more
TL;DR: In this article, a structural model for the cobaltite with three different oxidation states 2+, 3+, and 4+, in agreement with x-ray appearance near-edge structure spectra at the Co K edge was found.
Journal ArticleDOI
Structural and Magnetic Studies of Ordered Oxygen-Deficient PerovskitesLnBaCo2O5+δ, Closely Related to the “112” Structure
TL;DR: In this article, the influence of the oxygen content on the metal-insulator transition and the corresponding magnetic susceptibility anomaly is studied for LnBaCo2O5+δ with various oxygen stoichiometries.
Journal ArticleDOI
Magnetic phase diagrams of L 1 − x A x MnO 3 manganites ( L = P r , S m ; A = C a , S r )
TL;DR: In this article, the authors compared the magnetic phase diagrams of four compounds and showed that low $ ǫ-A$ values are required to obtain CMR properties on the rich side, i.e., when a competition between charge order and cluster glass phases occurs.
Journal ArticleDOI
Les oxydes A2BaCuO5 (A = Y, Sm, Eu, Gd, Dy, Ho, Er, Yb)
Claude Michel,B. Raveau +1 more
TL;DR: A series of new phases, A2BaCuO5 (A = Y, Sm, Eu, Gd, Dy, Ho, Er, Yb), has been isolated as mentioned in this paper.
Journal ArticleDOI
Insulator–Metal Transition Induced by Cr and Co Doping in Pr0.5Ca0.5MnO3
TL;DR: In this paper, it was shown that the doping of perovskite manganites with either chromium or cobalt induces an insulator to metal transition, which is exceptional since such a transition has not been observed to date in charge ordered manganite Ln 0.5 Ca 0.3 with an A-site cation of such a small size.
