“Researchers…have been able to prove the existence of a “spin battery,” a battery that is “charged” by applying a large magnetic field to nano-magnets in a device called a magnetic tunnel junction (MTJ)…The device…can store energy in magnets rather than through chemical reactions. Like a winding up toy car, the spin battery is “wound up” by applying a large magnetic field –no chemistry involved…”We had anticipated the effect, but the device produced a voltage over a hundred times too big and for tens of minutes, rather than for milliseconds as we had expected,”…” Full Slice
