Problem set on many-body physics that grew out of the course "Statistical Field Theory" can be found here.
The slides for the spintronics tutorial at the 2011 APS March Meeting can be found here.
Lecture notes on spintronics [Continuously-updated lecture notes and exercises that grew out of the course "spintronics" taught at Utrecht university in Spring 2007. Topics discussed are: path integrals for spins, ferromagnetism, spin valves, spin transfer torques, current and field-driven domain wall motion, and the spin Hall effect. There is also a short appendix on transport and disordered electrons. Feel free to use these notes but please refer appropriately.]
