Advancements in Electroplated Co-Pt Thick Film Micromagnets

There are enormous opportunities to employ permanent magnets to establish strong magnetic fields or field gradients in microsystem applications such as microactuators, microsensors, biological cell manipulation, micro power generators, etc. [1]. These applications motivate the development of microfabrication methods to realize high-remanence, high-coercivity magnetic structures in a dimensional “gap” between traditional bulk materials (usually >1 mm) and thin films (usually
