Researchers at the University of Miami and at the Universities of Tokyo and Tohoku, Japan, have developed what they call a "spin battery" which is "charged" by applying a large magnetic field to nano-magnets in a device called a magnetic tunnel junction (MTJ). In the future, the new battery could power cars and computers, say the researchers.
