1. A method of forming a micromagnetic device, comprising:
- providing a substrate; and
forming a magnetic core layer over said substrate from a magnetic alloy including iron, cobalt, phosphorous and at least one of sulfur, vanadium, tungsten and copper, wherein a content of said at least one of sulfur, vanadium, tungsten and copper is in a range of 1 to 100 parts per million, a content of said cobalt is in a range of 1.8 to 4.5 atomic percent, a content of said phosphorus is in a range of 20.1 to 30 atomic percent, and a content of said iron is substantially a remaining proportion of said magnetic alloy.
