摘要:
A magnetic material comprises 50-80 wt % of Cobalt, 9-15 wt% of Nickel, 10-25 wt% of Rhenium, 0.1 to 2.0 wt% of Phosphorus, and 5-10 wt % of Tungsten or Platinum. It can be formed as a layer having good vertical magnetic properties (e.g. when magnetised it can provide a high magnetic field strength in the direction perpendicular to the plane of the layer). The layer preferably has a thickness of above 1 mum. It can be formed by electroplating. The layer is useful for inclusion in a MEMS device.

PROBLEM TO BE SOLVED: To provide a method for manufacturing a cobalt iron alloy and a quaternary alloy which can improve magnetic properties, and a method for manufacturing a plated magnetic thin-film of a cobalt iron alloy and a plated magnetic thin-film of a cobalt iron molybdenum alloy. SOLUTION: The plated magnetic thin-film of a cobalt iron alloy includes an alloy having, for instance, the formula of Co100-a-b Fea Mb , (where, (a) and (b) are mass ratios in ranges of respectively satisfying 0 /(4π) A/m or less. The method for manufacturing such a plated magnetic thin-film includes employing a plating treatment through applying plating current of, for instance, direct current, pulse current, bipolar pulse current, pulse adjusting current, or these combinations.
