Abstract:
Systems and methods for controlling stray fields of a magnetic feature are provided. One such method can involve selecting a plurality of materials for a magnetic feature, selecting a plurality of additives, combining the plurality of materials for the magnetic feature and the plurality of additives in an electrolyte solution to form a combined solution, adding nitrogen to the combined solution, degassing the combined solution, depositing the combined solution as a thin film on a wafer using pulse plating, and lapping the thin film to form an edge of the magnetic feature. In several embodiments, the magnetic feature is a component of a magnetic transducer such as a writer pole, a reader shield, or a writer shield.
