Journal ArticleDOI
Experimental Evidence of the Néel-Brown Model of Magnetization Reversal
Wolfgang Wernsdorfer,E. Bonet Orozco,Klaus Hasselbach,Alain Benoit,Bernard Barbara,N. Demoncy,A. Loiseau,H. Pascard,Dominique Mailly +8 more
TL;DR: In this article, the first magnetization measurements of individual ferromagnetic nanoparticles (15-30 nm) at very low temperatures (0.1-6 K) were presented.
Journal ArticleDOI
Filling carbon nanotubes with metals by the arc-discharge method: the key role of sulfur
N. Demoncy,N. Demoncy,Odile Stéphan,Nathalie Brun,Christian Colliex,Christian Colliex,A. Loiseau,H. Pascard +7 more
TL;DR: In this paper, the structural characteristics of these encapsulated nanowires were studied by High Resolution Transmission Electron Microscopy and their chemical composition was investigated using Electron Energy-Loss Spectroscopy with high spatial resolution.
Journal ArticleDOI
Magnetisation reversal by uniform rotation (Stoner–Wohlfarth model) in FCC cobalt nanoparticles
TL;DR: The combination of high sensitive superconducting quantum interference device (SQUID) with high quality nanoparticles allowed to check the simplest classical model describing the magnetisation reversal by uniform rotation which were proposed more than 50 years ago by Neel, Stoner and Wohlfarth as discussed by the authors.
Journal ArticleDOI
Sulfur: the key for filling carbon nanotubes with metals
TL;DR: In this article, a growth mechanism based on a catalytic process involving carbon, a metal and sulfur was proposed for filling nanotubes with a graphite cathode and an anode doped with the filling element.
Journal ArticleDOI
Mesoscopic effects in magnetism: Submicron to nanometer size single particle measurements
Wolfgang Wernsdorfer,E. Bonet Orozco,Bernard Barbara,Klaus Hasselbach,Alain Benoit,Dominique Mailly,Bernard Doudin,J. Meier,Jean-Eric Wegrowe,J.-Ph. Ansermet,N. Demoncy,H. Pascard,Annick Loiseau,L. Francois,N. Duxin,M.P. Pileni +15 more
