Spin-triplet superconductivity in a ferromagnet

[phantom power]

PROVIDENCE, R.I., Feb. 15 (UPI) -- Rhode Island and Alabama scientists report creating, for the first time, a "spin triplet" supercurrent through a ferromagnet over a long distance.

Under quantum physics theory, conventional superconductivity is not supposed to occur in ferromagnets. When electrons pass through such crystalline materials, they realign in ways that won't allow resistance-free conductivity.

But scientists from Delft University of Technology, Brown University and the University of Alabama have now accomplished that physics feat, creating a "spin triplet" supercurrent through a unique ferromagnet.

"It's a beautiful thing," said Gang Xiao, a Brown professor of physics. "What we've done was considered almost impossible. But physicists never take 'no' for an answer."
