Fuckin A!!! An extremely sensitive nanoscale device has been built which creates a ballistic magneroresistance (BMR) that exhibited a record change in sensor resistance of more than 3,000% !!!!! But don't take my work for it, read for yourself. So what, you ask? Well, giant magnetoresistance (GMR) is so out you know? I just didnt want you to sound stupid at a party. I know how much GMR has been in everyone's minds in the last few years, but it's time to move on people.
