Abstract[English]
There is provided, in one example aspect, a magnetic core structure comprising a plurality of core portions that are made of a nanocrystalline material with a reduced magnetic permeability and that are stacked to reduce eddy currents. There is provided, in another aspect, a method of manufacturing a nanocrystalline material comprising: reducing a magnetic permeability of a nanocrystalline material; and forming a plurality of separate flakes in the nanocrystalline material.[French]
Dans un aspect donné à titre d'exemple, l'invention concerne une structure de noyau magnétique comprenant une pluralité de parties de noyau qui sont constituées d'un matériau nanocristallin ayant une perméabilité magnétique réduite et qui sont empilées pour réduire les courants de Foucault. Selon un autre aspect, l'invention concerne un procédé de fabrication d'un matériau nanocristallin comprenant : la réduction d'une perméabilité magnétique d'un matériau nanocristallin ; et la formation d'une pluralité de paillettes séparées dans le matériau nanocristallin.
