Electride and superconductivity behaviors in Mn5Si3-type intermetallics

Intermetallics: Superconductivity coexists with electride behavior Coexistence of electride behavior and superconductivity is observed in a hexagonal phase of a Nb5Ir3 intermetallic with tunable electronic properties by introducing foreign atoms. A team led by Yaoqing Zhang and Hideo Hosono from Jap...
