This Defense Intelligence Reference Document, dated 23 March 2010 and produced by the Defense Intelligence Agency under its Advanced Aerospace Weapon System Applications (AAWSA) program, is a technical report on metallic spintronics. It explains giant magnetoresistance, spin-transfer torque and antiferromagnetic spintronics, along with their uses in sensors, hard drive read heads and magnetic memory. It concludes that spintronic devices could enable low-power, radiation-resistant electronics suited to aerospace and long space missions.
