20140218122 | SPINTRONIC OSCILLATOR, AND USE THEREOF IN RADIOFREQUENCY DEVICES - An oscillator is provided including a nanopillar and current injector for injecting a power supply current through the nanopillar, the nanopillar including at least one pattern including first and second layers made from a ferromagnetic material separated from each other by an intermediate layer made from a non-magnetic material. Each of the first and second ferromagnetic layers is prepared such that its remanent magnetic configuration corresponds to a vortex configuration and the polarity of the vortex core of the first layer is opposite the polarity of the vortex core of the second layer. The intermediate layer can allow repellant magnetic coupling between the two vortices of the first and second layers, for a zero intensity of the power supply current and a zero amplitude of the outside magnetic field. | 08-07-2014 |
20100304006 | METHOD OF MANUFACTURING SILICA-COATED METAL NANOPARTICLES - A method of producing silica-coated metal nanoparticles with at least one tetraalkoxysilane, from nanoparticles, referred to as metal nanoparticles, includes a quantity of at least one metal of zero oxidation state, a quantity of a catalytic hydrolysis composition, a quantity of liquid solvent medium and a quantity of water, so as to obtain a hydrolysis/condensation enabling the metal nanoparticles to be coated with silica, wherein the liquid solvent medium consists of at least one solvent chosen from the group formed by non-alcoholic organic solvents. | 12-02-2010 |
