Polaronic effect in the x-ray absorption spectra of La1-x Ca x MnO3 manganites. [PDF]

open access: yes, 2019
X-ray absorption spectroscopy (XAS) is performed to study changes in the electronic structures of colossal magnetoresistance (CMR) and charged ordered (CO) La1-x Ca x MnO3 manganites with respect to temperature.

Low frequency 1/f noise in doped manganite grain-boundary junctions

open access: yes, 2002
We have performed a systematic analysis of the low frequency 1/f-noise in single grain boundary junctions in the colossal magnetoresistance material La_{2/3}Ca_{1/3}MnO_{3-delta}. The grain boundary junctions were formed in epitaxial La_{2/3}Ca_{1/3}MnO_{

Effect of Mn substitution by Ga on the optical properties of a metallic manganite

open access: yes, 2007
In a metallic manganite like La(2/3)Sr(1/3)MnO(3), the substitution of Mn(+3) by Ga(+3) dilutes the ferromagnetic order and locally cancels the Jahn-Teller distortion, without heavily affecting the crystal structure.

Recent Advances of Colossal Magnetoresistance in Versatile La-Ca-Mn-O Material-Based Films

open access: yesMagnetochemistry
Hole-doped manganese oxides exhibit a gigantic negative magnetoresistance, referred to as colossal magnetoresistance (CMR), owing to the interplay between double-exchange (DE) ferromagnetic metal and charge-ordered antiferromagnetic insulator ...

Evolution and control of the phase competition morphology in a manganite film

open access: yes, 2015
The competition among different phases in perovskite manganites is pronounced since their energies are very close under the interplay of charge, spin, orbital and lattice degrees of freedom.

Temperature dependence of Gilbert damping in manganite/normal metal heterostructure

open access: yesEPJ Web of Conferences, 2018
The temperature dependence of the spin-pumping effect on the Gilbert damping in a bilayer based on epitaxial manganite film grown on neodymium galate substrate was investigated by measuring of the linewidth of the ferromagnetic resonance spectrum (FMR ...

Charge localization at the interface between La1-xSrxMnO3 and the infinite layers cuprate CaCuO2

open access: yes, 2012
(CaCuO2)m/(La0.7Sr0.3MnO3)n superlattices, consisting of the infinite layers cuprate CaCuO2 and the optimally doped manganite La1-xSrxMnO3, were grown by pulsed laser deposition. The transport properties are dominated by the manganite block.
