International audience; We have investigated the magnetic behavior and the structural properties of ferromagnetic-antiferromagnetic systems (NiFe-IrMn and Co-IrMn) deposited directly on a thin tantalum buffer layer (bottom configuration) or above a t

We fabricated tunnel junctions containing clusters embedded in a thin insulating layer. Low-temperature dc transport measurements reveal typical Coulomb blockade features. We measured the differential capacitance at different dc voltages and frequenc

We study the growth by sputtering of Au clusters on amorphous Al2O3 using transmission electron microscopy (TEM). The weak decrease of the cluster density with temperature is a clear sign that the defects of the substrate strongly influence the growt

International audience; An original concept of high sensitivity magnetic field sensor using the spin-dependent tunneling effect has been investigated. The required crossed-biased configuration is obtained by combining both shape energy originating fr

Granular Co/AlN multilayers, with Co thicknesses varying from 0.2 to 3 nm, were prepared by sputtering. The goal was to prepare Co clusters embedded in a ceramic matrix and to study their magnetic properties. The local surrounding of the Co atoms was

We study the 3D growth of clusters during the deposition of Au atoms on amorphous ${\mathrm{Al}}_{2}{\mathrm{O}}_{3}$. By comparing transmission electron microscopy images of the growth with Monte Carlo simulations, we show that nucleation takes plac

We compare the 3D Monte-Carlo simulations of atom aggregation on a surface with TEM micrographs of real cobalt deposits obtained by sputter deposition on amorphous alumina. The discrepancy between deposited masses in otherwise similar calculated and

We have measured the resonant scattering from an antiferromagnetic Co/Cr multilayer at photon energies close to the cobalt 2p→3d transitions. The cobalt dielectric tensor has an anisotropic component, enhanced by resonance, which depends on the mag

We report on aggregation of Co on a smooth amorphous alumina surface, during sputter deposition of Co atoms at room temperature. The atomic structure of the Co grains appears to be size dependent: hep in the larger bean-shaped clusters (greater than

We report on the structure of cobalt cluster films obtained by aggregation of metal atoms sputter-deposited on amorphous alumina. The cluster layers were encapsulated with a second amorphous alumina layer, also made by sputtering in the same chamber.
