Fabrication of small superconducting coils using (Ba,A)Fe2As2 (A: Na, K) round wires with large critical current densities
Sunseng Pyon, Haruto Mori, Tsuyoshi Tamegai +6
We report the fabrication of small (Ba,A)Fe2As2 (A: Na, K) coils using 10 m-class long round wires, fabricated by powder-in-tube (PIT) method. Coils are sintered using hot-isostati…
Enhancement of critical current density in (Ba,Na)Fe2As2 round wires using high-pressure sintering
Sunseng Pyon, Daisuke Miyawaki, Tsuyoshi Tamegai +4
We fabricated (Ba,Na)Fe2As2 superconducting wires using the powder-in-tube method and hot isostatic pressing. By improving powder synthesis processes compared with previous studies…
Electronic structure of BaNiP observed by angle-resolved photoemission spectroscopy
S. Ideta, T. Yoshida, M. Nakajima +16
We have performed an angle-resolved photoemission spectroscopy (ARPES) study of BaNiP which shows a superconducting transition at 2.5 K. We observed hole and e…
Fermi surface in KFe2As2 determined via de Haas-van Alphen oscillation measurements
Taichi Terashima, Nobuyuki Kurita, Motoi Kimata +14
We have completely determined the Fermi surface in KFeAs via de Haas-van Alphen (dHvA) measurements. Fundamental frequencies , , , and are observed in KFeA…
Orbital-dependent electron correlation effect on the two- and three-dimensional Fermi surfaces in KFe2As2 revealed by angle-resolved photoemission spectroscopy
T. Yoshida, S. Ideta, I. Nishi +14
We have performed an angle-resolved photoemission study of the hole-overdoped iron pnictide superconductor KFe2As2, which shows a low Tc of ~4 K. Most of the observed Fermi surface…
High-Tc superconductivity and antiferromagnetism in multilayer cuprates: 63Cu- and 19F-NMR on five-layer Ba2Ca4Cu5O10(F,O)2
Sunao Shimizu, Shin-ichiro Tabata, Shiho Iwai +5
We report systematic Cu- and F-NMR measurements of five-layered high-Tc cuprates Ba2Ca4Cu5O10(F,O)2. It is revealed that antiferromagnetism (AFM) uniformly coexists with supercondu…
