The invention relates to a novel magnetic liquid and to a method and device for the production thereof. The aim of the invention is to produce a magnetic liquid which is based on a polar carrier liquid having a high saturation magnetization, i.e. having a high concentration of nanometer particles and a low viscosity, and to provide a method and device for the production thereof. To this end, a magnetic liquid is provided which comprises a saturation magnetization of at least 30 mT and a viscosity under 100 mPas at 40 ~C, whereby the carrier liquid contains essentially no dissolved components of the outer adsorption layer. In addition, a method and device are provided for the production thereof.
L'invention concerne un nouveau liquide magnétique, ainsi qu'un procédé et un dispositif permettant de le préparer. L'invention vise à mettre au point un liquide magnétique à base d'un liquide excipient polaire à forte aimantation à saturation, c.-à-d. avec une forte concentration en particules de l'ordre du nanomètre, et à viscosité réduite, ainsi qu'un procédé et un dispositif permettant de le préparer. A cet effet, il est prévu un liquide magnétique présentant une aimantation à saturation d'au moins 30 mT et une viscosité de moins de 100 mPas à 40 ·C. Le liquide excipient ne contient sensiblement pas de constituants dissous de la couche d'adsorption extérieure. Il est également prévu un procédé et un dispositif permettant de préparer ledit liquide.
