A traditional Josephson junction has two superconducting terminals. But researchers at Inac* recently looked at the theoretical behavior of four-terminal junctions—and the idea was an excellent one! The researchers predicted that, by applying a different voltage to two of the terminals, they would obtain the alternative current that characterizes the Josephson effect and a totally […] >>

Researchers at Spintec have achieved skyrmions that are stable at ambient temperature and without a magnetic field. The researchers deposited a magnetic layer of cobalt several atoms thick between a layer of platinum and a layer of magnesium oxide. The resulting structure significantly increases the magnetic interaction that underpins the skyrmion’s helicoidal structure. The skyrmion—a […] >>
