Posttreatment Effects on the Crystal Structure and Superconductivity of Ca-Free Double-Layered Cuprate SrSrCuOF
Hiroki Ninomiya, Kenji Kawashima, Hiroshi Fujihisa +6
We report the effects of low-temperature postannealing on the structural and superconducting properties of the recently discovered Ca-free double-layered cuprate, SrSrCuO$_…
Antiperovskite superconductor LaPdP with noncentrosymmetric cubic structure
Akira Iyo, Izumi Hase, Hiroshi Fujihisa +8
Antiperovskites are a promising candidate structure for the exploration of new materials. We discovered an antiperovskite phosphide, LaPdP, following our recent synthesis of…
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…
Superconductivity of centrosymmetric and non-centrosymmetric phases in antiperovskite (Ca,Sr)PdP
Akira Iyo, Izumi Hase, Hiroshi Fujihisa +9
In the recently discovered antiperovskite phosphide (Ca,Sr)PdP, centrosymmetric (CS) and non-centrosymmetric (NCS) superconducting phases appear depending on the Sr concentrati…
Observation of Kondo hybridization with an orbital-selective Mott phase in 4d Ca2-xSrxRuO4
Minsoo Kim, Junyoung Kwon, Choong H. Kim +12
The heavy fermion state with Kondo-hybridization (KH), usually manifested in f-electron systems with lanthanide or actinide elements, was recently discovered in several 3d transiti…
