Enhanced Superconductivity in Close Proximity to the Structural Phase Transition of Sr1-xBaxNi2P2
Kazutaka Kudo, Yutaka Kitahama, Keita Iba +2
The structural evolution and superconductivity of a 122-type solid solution Sr1-xBaxNi2P2 were studied. We found that an orthorhombic-tetragonal structural phase transition takes p…

Emergence of superconductivity at 45 K by lanthanum and phosphorus co-doping of CaFe2As2
Kazutaka Kudo, Keita Iba, Masaya Takasuga +5
Co-doping of lanthanum and phosphorus in CaFe2As2 induces superconductivity at 45 K. This superconducting transition temperature is higher than the 38 K transition in Ba1-xKxFe2As2…
