For the first time, scientists have created a â€śspin tripletâ€? supercurrent through a ferromagnet over a long distance. Achieved with a magnet developed at Brown University and the University of Alabama, the feat upends long-standing theories of quantum physics â€“ and may be a boon to the budding field of â€śspintronics,â€? where the spin of electrons, along with their charge, is harnessed to power computer chips and circuits. Results are published in Nature.
