Document Type and Number:
Japanese Patent JP2007180532
Kind Code:
A
Abstract:
To provide a magnetic structure suitable for a micro magnetic device, and a method for manufacturing the magnetic structure.
A hard magnetic film of out-of-plane having a cobalt-platinum-phosphorous (CoPtP) composition doped with a tungsten (W) is formed by electroplating of dc constant current electrodeposition, and laminated into a multi-layer structure with an intermediate layer of Au between, and then annealed in air.
