http://www.freepatentsonline.com/8003497.html

This patent from the Regents of the University of California teaches a way to fabricate magnetic nanowires for application in spintronic hard drives. Claim 1 reads:

1. A method for fabricating diluted magnetic semiconductor (DMS) nanowires, comprising:

providing a catalyst-coated substrate; and

subjecting at least a portion of the substrate to a semiconductor-based solution and a dopant-based solution;

wherein said dopant-based solution comprises a dopant and a chloride-based vapor transport to aid in synthesis of the magnetic semiconductor nanowires.
