Magnon-polaron and Spin-polaron Signatures in the Specific Heat and Electrical Resistivity of $L a_{0.6} Y_{0.1} C a_{0.3} M n O_{3}$ in Zero Magnetic Field, and the Effect of $M n - O - M n$ Bond Environment

M. Ausloos, L. Hubert, S. Dorbolo +2

$L a_{0.6} Y_{0.1} C a_{0.3} M n O_{3}$ , an $A B O_{3}$ perovskite manganite oxide, exhibits a non trivial behavior in the vicinity of the sharp peak found in the resistivity $ρ$ as a funct…

Degradation of LaMnO{3-y} surface layer in LaMnO{3-y}/ metal interface

A. Plecenik, K. Frohlich, J. P. Espinos +4

We report electrical measurements showing the degradation processes of LaMnO $_{3 - y}$ (LaMnO) in LaMnO/normal metal interface in both point contact and planar-type junctions. Immedi…

Negative magnetoresistance in La(0.6)Y(0.1)Ca(0.3)MnO(3): Evidence for charge localization governed by the Curie-Weiss law

S. Sergeenkov, H. Bougrine, M. Ausloos +1

Colossal negative magnetoresistance Δρ(T,B) observed in La(0.6)Y(0.1)Ca(0.3)MnO(3) at B=1T shows a nearly perfect symmetry around T_0=160K suggesting a universal field-induced tran…
