Structural properties of epitaxial nanometric iron oxide layers on α-Al2O3(0001): an in situ RHEED study during growth
Autor: Susana Gota, Michèle Henriot, Eric Guiot, Martine Gautier-Soyer
Publikováno v: Surface Science. :796-801
By means of atomic oxygen molecular beam epitaxy (MBE), nanometric layers of different iron oxide phases have been epitaxially grown on the α-Al2O3(0001) surface. The evolution of their structural properties during growth has been studied in situ by

A LEED study of the (0001) a-quartz surface reconstruction
Autor: Martine Gautier, Florence Bart
Publikováno v: Surface Science. 311:L671-L676
This paper presents a low energy electron diffraction study of the α-SiO 2 (0001) surface structure modifications induced by thermal treatments under air. A reconstruction was observed as soon as the air heating temperature was greater than 600°C.

alpha-Al2O3 (0001) Surfaces: Atomic and Electronic Structure
Autor: Gilles Fenaud, Martine Gautier, J.P. Duraud, Maud Pollak, Bruno Villette, François Jollet, Laurent Pham Van, Nathalie Thromat
Publikováno v: Journal of the American Ceramic Society. 77:323-334
New results on the R± 9° reconstructed α-Al2O3 (0001) surface, which can be obtained after heating at high temperature (1400°C) under vacuum, are presented. The atomic structure has been studied by combining low-energy electron diffractometry and

Monensin-induced accumulation of neosynthesized lipids and fatty acids in a Golgi fraction prepared from etiolated leek seedlings
Autor: Claude Cassagne, Hélène Juguelin, Patrick Moreau, Pascal Bertho, Martine Gautier
Publikováno v: Biochimica et Biophysica Acta (BBA) - Biomembranes. 978:91-96
The effects of monensin on the intracellular distribution of neosynthesized lipids and fatty acids between different membrane fractions prepared from etiolated leek seedlings, were investigated. The penetration of the drug into the seedlings was meas

Condensed Matter [cond-mat]. Université Pierre et Marie Curie-Paris VI, 2008. English
The spin filtering effect is a phenomenon, which can potentially produce highly spin-polarized electron currents by the spin-selective transport of electrons across a magnetic tunnel barrier. In this thesis, we present a study of the material cobalt

Etude des propriétés physiques des films de Fe3O4 épitaxiés et de la polarisation en spin à l'interface Fe3O4/γ-Al2O3
Autor: Bataille, Alexandre
Publikováno v: Matière Condensée [cond-mat]. Université Paris Sud-Paris XI, 2005. Français. ⟨NNT : ⟩
Magnetite Fe3O4 is a promising material for spintronics since band structure calculations predict it to be half-metallic. One thus expect large magnetoresistance in magnetic tunnel junctions using Fe3O4 as electrode. We have grown 3 to 50 nm-thick Fe
