Title:
MAGNETIC DEVICES COMPRISING MAGNETIC META-MATERIALS
Document Type and Number:
WIPO Patent Application WO2003003385
Kind Code:
A3
Abstract:
A magnetic device (23) is made by joining magnetic sheet layers (20) that will react to join the layers into a unitary body. The joining materials are reacted, and the device is formed. In a preferred embodiment, the magnetic material is a soft magnetic material such as FeCo alloy, and the reactive joining materials are aluminum and FeCoOx which react to form nonconducting alumina layers between magnetic regions.
