The invention concerns a method for generating a pulsed magnetic field, the method being implemented using a device () comprising an electrical supply (), a switch (), a capacitor () and a coil () having a first extremity () connected to an electrical ground and a second extremity (), the capacitor () comprising a first electrode connected to the electrical ground and a second electrode, the switch () being able to commute between a first configuration wherein the second electrode and the second extremity () are electrically insulated and at least one second configuration wherein the second electrode and the second extremity () are electrically connected, the capacitor (), the switch () and the coil () forming a series circuit when the switch () is in the second configuration, the series circuit being underdamped.

Method for generating a pulsed magnetic field and associated device

A method for capturing a molecule in a sample, comprising mixing the sample with magnetic particles. Each of the particles being coupled with an element capable of binding selectively to the molecule for capture, so as to form at least one complex comprising a magnetic particle. The element and the molecule bound to the element, immobilizing the at least one complex on a support comprising ordered magnetic field microsources.

Method for capturing, method for detecting and kit for capturing a molecule in a sample

A method for producing a film including a non-magnetic matrix and a plurality of three-dimensional magnetic microstructures arranged within the matrix according to a predetermined pattern. The method includes providing a master substrate with a magnetically structured face formed from a plurality of magnetic field micro-sources, having a magnetic field gradient of between 10and 10T/m. The method also includes adding magnetic microparticles or nanoparticles to the magnetically structured face of the master substrate, the particles agglomerating into three-dimensional microstructures arranged under an effect of an attractive magnetophoretic force exerted by the magnetic field gradient on the surface of the master substrate. The method further includes depositing, on the magnetically structured face of the master substrate, a matrix made from a non-magnetic material, in such a way as to enclose the arranged microstructures and to form the film and peeling the film from the master substrate.

Method for producing a film comprising three-dimensional magnetic microstructures

A rare earth magnet, which is represented by a neodymium magnet (NdFeB) and neodymium magnet films with applications in micro-systems. A method for producing a rare earth magnet, comprising: (a) quenching a molten metal having a rare earth magnet composition to form quenched flakes of nanocrystalline structure; sintering the quenched flakes; subjecting the sintered body obtained to an orientation treatment; and applying a heat treatment with pressurization at a temperature sufficiently high to enable diffusion or fluidization of a grain boundary phase and at the same time, low enough to prevent coarsening of the crystal grains, (b) thick films deposited on a substrate, applying an annealing to crystallize with pressurization at a temperature sufficiently high to enable diffusion or fluidization of a grain boundary phase and, at the same time, low enough to prevent coarsening of the crystal grains.
