Researchers build SQUID device that demonstrates the Josephson effect

Italian nano-science researchers Francesco Giazotto and María José Martínez-Pérez have built a superconducting quantum interference device (SQUID) that confirms a theory that describes the Josephson effect, whereby the application of a magnetic field applied to such a device can cause changes in the amount of heat that flows through it. They describe their device and how it works in a paper they've published in the journal Nature.
