Commensurate magnetic structures ofRMn2O5 (R=Y, Ho, Bi) determined by Single-crystal Neutron Diffraction Open

C. Chapon, P. J. Brown, Tapan Chatterji, Seon-Hwan Cheong, P. G. Radaelli · 2007

Precise magnetic structures of RMn2O5, with R= Y, Ho, Bi in the commensurate/ferroelectric regime, have been determined by single-crystal neutron diffraction. For each system, the integrated intensities of a large number of independent mag…

HRTEM Studies of the Epitaxial Growth of Pd Particles (1-6 nm) on ZnO Micro-Prisms Open

Suzanne Giorgio, Claude R. Henry, C. Chapon · 1995

Materials science Chemistry

\nPd particles ($1-6$ nm) were grown under UHV conditions \nfrom a Knudsen \ncell, on small ZnO prisms in situ prepared in a controlled\natmosphere. 3-D Pd particles epitaxially oriented on the ZnO\nfaces were observed by HRTEM, both in to…

STM/TEM comparative study of Pd clusters epitaxially grown on highly oriented pyrolytic graphite Open

Samuel Granjeaud, K. Yckache, M. Dayez, A. Humbert, C. Chapon , et al. · 1993

Materials science Chemistry Engineering

Pd clusters in the size range 1-100 nm are grown at high temperature on HOPG and observed by STM and TEM. These two techniques give complementary information. The morphology of the particles is easily obtained by STM at all sizes, while TE…

Résume.2014 De petites particules métalliques cristallisées sur des cubes de MgO ont été observées de profil par MEHR.Les images de haute résolution sont traitées numériquement pour améliorer les contrastes de la morphologie des particules…

Experimental image processing of small supported metallic particles (1-3 nm) Open

Suzanne Giorgio, Geneviève Nihoul, C. Chapon, Claude R. Henry · 1991

Materials science Chemistry Computer science

Metallic particles crystallized on MgO cubes have been observed in profile view in HRTEM. The images are processed in order to improve the visibility of the particles morphology and the eventual defects at the interface metal/MgO. Three di…
