Physics Nobel: Giant Magnetoresistance

Having gotten that silly Medicine business out of the way, the Swedish Academy has moved on to the important Award, with the 2007 Nobel Prize in Physics going to Albert Fert and Peter Grunberg for the discovery of Giant Magnetoresistance. This is one that people have been calling for for a while, now.

I’ll try to give a more complete explanation of what this is and why it’s important later, but I’m going to Boston with a student group today, and I need to run to catch the bus. I’ll just note quickly that this should be applauded by blog readers, because GMR is an enabling technology for better hard drives.

Feel free to post better explanations, or links to explanations, in the comments while I’m gone.
