Hey all,
First of all, I'm not sure if this is in the right forum-- if not, sorry about that .
I am doing a presentation on Spintronics as part of my 2nd year Physics coursework at University.
In researching, I see that there is a great link between the Giant Magnetoresistance Effect (GMR) and Spintronics. Now to me, the processes seem more or less similar -- changing the spin with magnetic field and writing information.
My question is this: GMR-based devices have been here for a while, such as hard drives, read heads etc... so then WHY is Spintronics said to be such a new field? How exactly are the GMR devices different from the more recent developments in Spintronics??
Thanks.
