Journal ArticleDOI
Macroscopic quantum tunnelling of magnetization in a single crystal of nanomagnets
TL;DR: In this article, the results of low-temperature experiments on a single crystal composed of superparamagnetic manganese clusters (Mn12-ac) were reported, which clearly demonstrate the existence of quantum-mechanical tunnelling of the bulk magnetization.
Journal ArticleDOI
Macroscopic quantum tunneling in molecular magnets
TL;DR: In this article, a review of the present understanding of the phenomenon of quantum tunneling of magnetization (QTM) is reviewed in the light of the experiments performed on the molecular complex Mn 12 -ac.
Journal ArticleDOI
Thermally assisted macroscopic quantum resonance on a single-crystal of Mn12-acetate
F. Lionti,Luc Thomas,Rafik Ballou,Bernard Barbara,André Sulpice,Roberta Sessoli,Dante Gatteschi +6 more
TL;DR: In this article, a single monocrystal of the molecule Mn12-acetate (Mn12Ac) was used to perform magnetization measurements on a single manganese cluster.
Journal ArticleDOI
Quantum resonance of the magnetisation in a single-crystal of Mn12-ac
TL;DR: In this paper, the authors raise a few questions regarding the hypothesis of conservation of the collective spin in molecular crystals, some of them of interest for a deeper understanding of resonant tunnelling in Mn 12 -ac.
Journal ArticleDOI
Dynamical properties of non-interacting Co nanoparticles
Marc Respaud,M. Goiran,J.M. Broto,F. Lionti,Luc Thomas,Bernard Barbara,T. Ould Ely,Catherine Amiens,Bruno Chaudret +8 more
TL;DR: In this article, the authors investigated the magnetic moment of noninteracting cobalt nanoparticles dispersed in a polymer and estimated the relaxation time of the magnetisation associated to the superparamagnetic properties of the particles.
