Travis, Look to the magnetic recording industry for information on magnetic alloys. Plating (of say, NiFe) is a typical method for putting down magnetic films onto a substrate. I have seen compositions range from 80/20 to 45/55 depending on the magnetic field requirements. I hope this helps.

I want to fabricate some structures using iron or iron oxide. But I don't know what is the conventional method to grow a iron/iron oxide film? Is iron an incompatible material for MEMS? Why there's so little literature about it? If I can't use iron, what are some most commonly used magnetic materials in MEMS? I know nickel is one of them. Thank you so much for your help!
