Structure determination of a brownmillerite Ca2Co2O5 thin film by Precession Electron Diffraction
P. Boullay, V. Dorcet, O. Perez +4
Calcium cobaltite thin films with a ratio Ca/Co=1 were grown on (101)-NdGaO3 substrate by the pulsed laser deposition technique. The structure of the deposited metastable phase is…
Magnetic states and spin-glass properties in Bi0.67Ca0.33MnO3: macroscopic ac measurements and neutron scattering
M. Giot, A. Pautrat, G. Andre +3
We report on the magnetic properties of the manganite Bi_{1-x}Ca_{x}MnO_3 (x=0.33) at low temperature. The analysis of the field expansion of the ac susceptibility and the observat…
Absence of long-range Ni/Mn ordering in ferromagnetic La2NiMnO6 thin films
M. P. Singh, C. Grygiel, W. C. Sheets +6
Epitaxial La2NiMnO6 thin films have been grown on (001)-oriented SrTiO3 using the PLD technique. The thin films are semiconducting and FM with a TC close to 270K, a coercive field…
Structural phase transition and magnetism in hexagonal srmno
A. Daoud-Aladine, C. Martin, L. C. Chapon +4
The structural and magnetic properties of the hexagonal four-layer form of SrMnO have been investigated by combining magnetization measurements, electron diffraction and high-r…
Enhancement of giant magnetoresistance effect in the Ruddlesden-Popper phase Sr3Fe2-xCoxO7-d: Predominant role of oxygen nonstoichiometry and magnetic phase separation
T. Motohashi, B. Raveau, M. Hervieu +4
The magnetic and magnetotransport properties of the Sr3Fe2-xCoxO7-d system (0.2 <= x <= 1.0) were systematically investigated. This oxide system exhibits a giant magnetoresistance…
Competition between ferromagnetism and spin glass: the key for large magnetoresistance in oxygen deficient perovskites SrCo1-xMxO3-d (M = Nb, Ru)
T. Motohashi, V. Caignaert, V. Pralong +3
The magnetic and magnetotransport properties of the oxygen deficient perovskites, SrCo1-xMxO3-d with M = Nb and Ru, were investigated. Both Nb- and Ru-substituted cobaltites are we…
