Strong-Coupling Superconductivity in BaPd2As2 Induced by Soft Phonons in the ThCr2Si2-type Polymorph
Kazutaka Kudo, Yoshiaki Yamada, Takaaki Takeuchi +5
The specific heat of two polymorphs of BaPd2As2 was measured. The ThCr2Si2-type polymorph (space group I4/mmm, , No. 139) is a previously reported superconductor with…
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…
Site-Selective Antimony Doping in Arsenic Zigzag Chains of 112-type Ca1-xLaxFeAs2
Hiromi Ota, Kazutaka Kudo, Takumi Kimura +4
Single crystal X-ray diffraction studies were performed for the Sb-doped 112-type iron-based superconductor Ca1-xLaxFeAs2 with the superconducting transition temperature Tc of 47 K…
Superconducting Transition Temperatures of up to 47 K from Simultaneous Rare-Earth Element and Antimony Doping of 112-Type CaFeAs2
Kazutaka Kudo, Yutaka Kitahama, Kazunori Fujimura +3
The effects of simultaneous Sb doping on the superconductivity of 112-type Ca1-xRExFeAs2 (RE = La, Ce, Pr, and Nd) were studied through measurements of the magnetization and electr…
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…
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…
