More Information
Summary:The invention relates to a composite magnetic sheet material comprising at least one thin support film of polymer, which is mechanically and thermally resistant, coated on at least one of its faces with a thin deposit of a ferromagnetic amorphous compound having a magnetic permeability higher than 30, the density d and the permeability of the composite magnetic material being such that 5 </= mu /d </= 100. L'invention se rapporte à un matériau magnétique composite en feuilles comportant au moins un film support mince de polymère, résistant mécaniquement et thermiquement, revêtu sur au moins une de ses faces d'un dépôt mince d'un composé amorphe ferromagnétique ayant une perméabilité magnétique supérieure à 30, la densité d et la perméabilité du matériau magnétique composite étant telles que 5<=mu /d<=100.
