Refreshments will be served at 3:30 PM in the lounge.
All interested persons are cordially invited to attend.
Conventional electronics manipulates the charge of the electron for useful purposes. Spintronics seeks to do the same thing with the electron's spin degree of freedom. Although the long-range hope is to integrate spin manipulation with semiconductor technology, the greatest successes so far are associated with all-metal ferromagnetic heterostructures known as "spin valves". The key effect at work is the remarkable ability of a spin-polarized electric current to reverse the magnetization of a small magnetic element. An optical analogy will be used to explain this intrinsically quantum mechanical effect and its consequences.
