  • Conducting fluid containing micrometric magnetic particles
    Patent number: 8404139
    Abstract: The invention relates to a composite material formed by microparticles of magnetic material A and a conductive liquid B. The material is characterized in that the material A is chosen from magnetic compounds and magnetic alloys and is in the form of particles, the mean size of which is between 1 and 10 ?m, and in that the support fluid B is a conductive fluid chosen from metals, metal alloys and salts that are liquid at temperatures below the Curie temperature of the material A, or from mixtures thereof.
    Type: Grant
    Filed: June 26, 2006
    Date of Patent: March 26, 2013
    Assignees: Universite Pierre et Marie Curie, Centre National de la Recherche Scientifique
    Inventors: Emmanuelle Dubois, Jean Chevalet
  • Conducting fluid containing millimetric magnetic particles
    Patent number: 8404140
    Abstract: The invention relates to a composite material formed by millimeter-scale particles of magnetic material A and a conductive liquid B. The material is characterized in that the material A is chosen from magnetic compounds and magnetic alloys and is in the form of particles, the mean size of which is between 0.1 and 2 mm, and in that the support fluid B is a conductive fluid chosen from metals, metal alloys and salts that are liquid at temperatures below the Curie temperature of the material A, or from mixtures thereof.
