New work used high pressure and temperature to reveal a kind of “structural memory” in samples of bismuth, a discovery with great electrical engineering potential. Bismuth is a historically interesting element for scientists, as a number of important discoveries in the metal physics world were made while studying it, including important observations about the effect of magnetic fields on electrical conductivity. Bismuth has a number of phases...

This achievement will lead to a new field of study, strong correlated quantum transport of Dirac electrons, and become an innovation in realizing super high speed spintronics, the foundation of high-speed and energy-saving electronics.
A/Prof Hideaki Sakai at Osaka University and A/Prof Shintaro Ishiwata, Hidetoshi MASUDA (Grad Student) at Uni of Tokyo succeeded in the synthesis of high-quality single crystals of EuMnBi2, a layered compound which is thought to have both properties of Dirac fermions and magnets, using flux growth in a high vacuum...
