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…
Superconductivity in Ca1-xLaxFeAs2: A Novel 112-Type Iron Pnictide with Arsenic Zigzag Bonds
Naoyuki Katayama, Kazutaka Kudo, Seiichiro Onari +9
We report superconductivity in the novel 112-type iron-based compound Ca1-xLaxFeAs2. Single-crystal X-ray diffraction analysis revealed that the compound crystallizes in a monoclin…
Enhanced Superconductivity up to 43 K by P/Sb Doping of Ca1-xLaxFeAs2
Kazutaka Kudo, Tasuku Mizukami, Yutaka Kitahama +6
The effects of isovalent doping on the superconducting transition temperature Tc in novel 112-type iron arsenide Ca1-xLaxFeAs2 were studied by conducting measurements of electrical…
Superconductivity Induced by Breaking Te2 Dimers of AuTe2
Kazutaka Kudo, Hiroyuki Ishii, Masaya Takasuga +5
Mineral calaverite AuTe2 is a layered compound with an incommensurately modulated structure. The modulation is characterized by the formation of molecular-like Te2 dimers. We have…
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…
