Here's an introductory lecture on some aspects of spintronics from 2013 by Stuart Parkin of IBM: https://www.youtube.com/watch?v=cID4fKraWkE https://www.youtube.com/watch?v=cID4fKraWkE One application that he discusses is IBM's use of spintronics in the read heads of hard drives (i.e., spinning rust), which allowed them to increase sensitivity and to increase the storage density of the disks. Also, spin transfer torque (https://en.wikipedia.org/wiki/Spin-transfer_torque https://en.wikipedia.org/wiki/Spin-transfer_torque) is one technique for implementing magnetoresistive memory (MRAM) ( https://en.wikipedia.org/wiki/Magnetoresistive_random-access_memory https://en.wikipedia.org/wiki/Magnetoresistive_random-access...), which some people find exciting for its promise of DRAM-like read/write/erase speeds with data that persists after powered off.
