Superconductivity in Hexagonal BaPtAs: SrPtSb- and YPtAs-type Structures with Ordered Honeycomb Network
Kazutaka Kudo, Takaaki Takeuchi, Hiromi Ota +4
The crystal structure and superconductivity of hexagonal BaPtAs are reported. Single-crystal X-ray diffraction, magnetization, electrical resistivity, and specific heat measurement…
Pressure-Induced Superconductivity from Doping-Induced Antiferromagnetic Phase of 112-type CaLaFeAs
Shunsaku Kitagawa, Taishi Sekiya, Yo Fujiyoshi +8
The effects of pressure on antiferromagnetic (AFM) and superconducting phase transitions of 112-type CaLaFeAs were studied, and the in-plane electrical resistiv…
Superconductivity in MgPtSi: An orthorhombic variant of MgB2
Kazutaka Kudo, Kazunori Fujimura, Seiichiro Onari +2
A ternary compound, MgPtSi, was synthesized by solid-state reaction. An examination of the compound by powder X-ray diffraction revealed that it crystallizes in the orthorhombic Ti…
Suppression of superconductivity and structural phase transition against pressure in Ca(IrAs)(FeIrAs)
Shunsaku Kitagawa, Shingo Araki, Tatsuo C. Kobayashi +5
We measured the pressure dependence of in-plane resistivity in the recently-discovered iron-based superconductor Ca(IrAs)(FeIrAs)$_{…
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…
