Journal ArticleDOI
Magnetoresistance and collective Coulomb blockade in superlattices of ferromagnetic CoFe nanoparticles
Reasmey P. Tan,Julian Carrey,Céline Desvaux,Lise-Marie Lacroix,Philippe Renaud,Bruno Chaudret,Marc Respaud +6 more
TL;DR: In this paper, the magnetotransport properties of chemically synthesized magnetic artificial solids consisting of millimeter-size superlattices of CoFe nanoparticles (NPs) separated by a thin organic insulating layer were investigated.
Journal ArticleDOI
Shubnikov–de Haas oscillations in CoSb 3 single crystals
TL;DR: In this paper, the Shubnikov-de Haas (SdH) effect has been studied in single-crystal samples of the CoSb in pulsed magnetic fields up to 35 T. From the temperature dependence of the amplitude of the SdH oscillations the values of cyclotron effective mass were determined.
Journal ArticleDOI
Towards MRI T2 contrast agents of increased efficiency
Marlène Branca,Marlène Branca,Marzia Marciello,Diana Ciuculescu-Pradines,Diana Ciuculescu-Pradines,Marc Respaud,María del Puerto Morales,Raphael Serra,Marie-José Casanove,Catherine Amiens,Catherine Amiens +10 more
TL;DR: In this article, the effects of surface coating on the efficiency of two different types of iron-based nanoparticles (NPs) as MRI contrast agents were reported, and the relaxivities of their stable colloidal solutions in water were determined.
Journal ArticleDOI
Charge transport and interdot coupling tuned by the tunnel barrier length in assemblies of nanoparticles surrounded by organic ligands
Julien Dugay,Reasmey P. Tan,Mona Ibrahim,Cécile Garcia,Julian Carrey,Lise-Marie Lacroix,Pier-Francesco Fazzini,Guillaume Viau,Marc Respaud +8 more
TL;DR: In this paper, the effect of interdot coupling on the electronic transport was investigated on arrays of metallic nanoparticles coated by alkylamines, and it was shown that the temperature and bias dependence of the resistivity are governed by the length of the organic barriers and are well described by theories that consider inelastic cotunneling to be the main mechanism of interparticle transfer.
Journal ArticleDOI
Silica coated iron/iron oxide nanoparticles as a nano-platform for T2 weighted magnetic resonance imaging
Paul Mathieu,Yannick Coppel,Marc Respaud,Quyen Nguyen,Sébastien Boutry,Sophie Laurent,Dimitri Stanicki,Céline Henoumont,Fernando Novio,Julia Lorenzo,David Montpeyó,Catherine Amiens +11 more
TL;DR: Ten nm large Fe@FeOx nanoparticles are synthesized, coating with a 11 nm thick layer of dense silica and functionalization by 5 kDa PEG chains to improve their biocompatibility and display high r2 relaxivity values and low r1 leading to enhanced r2/r1 ratios in comparison with RESOVIST®.
