Charge-orbital-lattice coupling effects in the dd-excitation profile of one dimensional cuprates
J. J. Lee, B. Moritz, W. S. Lee +12
We identify dd-excitations in the quasi-one dimensional compound CaYCuO using resonant inelastic x-ray scattering. By tuning across the Cu L-edge, we observe…
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…
Superconductivity in Ca10(Ir4As8)(Fe2As2)5 with Square-Planar Coordination of Iridium
Kazutaka Kudo, Daisuke Mitsuoka, Masaya Takasuga +10
We report the unprecedented square-planar coordination of iridium in the iron iridium arsenide Ca10(Ir4As8)(Fe2As2)5. This material experiences superconductivity at 16 K. X-ray pho…
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…
Pressure-Induced Superconductivity in Mineral Calaverite AuTe2
Shunsaku Kitagawa, Hisashi Kotegawa, Hideki Tou +4
The pressure dependences of resistivity and ac susceptibility have been measured in the mineral calaverite AuTe. Resistivity clearly shows a first-order phase transition into a…
Enhancing high-temperature thermoelectric properties of PtAs2 by Rh doping
Kazutaka Kudo, Seiya Nakano, Tasuku Mizukami +2
The effects of Rh doping on the thermoelectric properties of Pt1-xRhxAs2 (x = 0, 0.005, and 0.01) with pyrite structure were studied by conducting measurements of electrical resist…
