An article comprising a multilayered structure 100 comprising a series of magnetic layers 110 is provided. The magnetic layers comprise a magnetic material, and an insulating layer 120 is disposed between successive magnetic layers. Each magnetic layer has a thickness of at least 2 micrometers and magnetic material has an average grain size not more than 200 nm, through different dimensions are possible. The magnetic layers may comprise a soft magnetic material such as Fe or Co and may contain nanadispersoids. Methods of manufacturing the article are provided, such as electron beam physical vapour deposition EBPVD. |
