Ames Laboratory scientists discover new family of quasicrystals

Scientists at the U.S. Department of Energy’s (DOE) Ames Laboratory have discovered a new family of rare-earth quasicrystals using an algorithm they developed to help pinpoint them.  Their research resulted in finding the only known magnetic rare earth icosahedral binary quasicrystals, now providing a “matched set†of magnetic quasicrystals and their closely related periodic cousins.

Resistivity switch is window to role of magnetism in iron-based superconductors

Physicists at the U.S. Department of Energy’s Ames Laboratory have discovered surprising changes in electrical resistivity in iron-based superconductors. The findings, reported in Nature Communications, offer further evidence that magnetism and superconductivity are closely related in this class of novel superconductors.
