Dependences on RE of Superconducting Properties of Transition Metal co-doped (Ca,RE)FeAs2 with RE = La-Gd
Hiroyuki Yakita, Hiraku Ogino, Alberto Sala +6
Dependence of superconducting properties of (Ca,RE)(Fe,TM)As2 [(Ca,RE)112, TM: Co, Ni)] on RE elements (RE = La-Gd) was systematically investigated. Improvement of superconducting…
Co-co-doping effect for (Ca,RE)FeAs2 sintered bulk
Hiroyuki Yakita, Hiraku Ogino, Alberto Sala +5
Superconducting properties of Co-co-doped (Ca,RE)FeAs2 ((Ca,RE)112: RE = La, Pr) were investigated. Co-co-doping increased Tc of (Ca,Pr)112 while Mn-co-doping suppressed supercondu…
Effects of post-annealing and cobalt co-doping on superconducting properties of (Ca,Pr)Fe2As2 single crystals
Tomoyuki Okada, Hiraku Ogino, Hiroyuki Yakita +3
In order to clarify the origin of anomalous superconductivity in (Ca,RE)Fe2As2 system, Pr doped and Pr,Co co-doped CaFe2As2 single crystals were grown by the FeAs flux method. Thes…
Synthesis and physical properties of Ca1-xRExFeAs2 with RE = La ~ Gd
Alberto Sala, Hiroyuki Yakita, Hiraku Ogino +10
Synthesis of a series of layered iron arsenides Ca1-xRExFeAs2 (112) was attempted by heating at 1000 C under a high-pressure of 2 GPa. The 112 phase successfully forms with RE = La…
Discovery of New Layered Iron Arsenide Superconductor (Ca,Pr)FeAs2
Hiroyuki Yakita, Hiraku Ogino, Tomoyuki Okada +9
A new iron-based superconductor (Ca,Pr)FeAs2 was discovered. Plate-like crystals of the new phase were obtained and crystal structure was investigated by single-crystal X-ray diffr…
