Pressure Effects on Superconducting Properties of the BiS2-Based Superconductor Bi2(O,F)S2
Tomoyuki Okada, Hiraku Ogino, Jun-ichi Shimoyama +5
Pressure effects on a recently discovered BiS2-based superconductor Bi2(O,F)S2 (Tc = 5.1 K) were examined via two different methods; high pressure resistivity measurement and high…
Topotactic synthesis of a new BiS2-based superconductor Bi2(O,F)S2
Tomoyuki Okada, Hiraku Ogino, Jun-ichi Shimoyama +1
A new BiS2-based superconductor Bi2(O,F)S2 was discovered. This is a layered compound consisting of alternate stacking structure of rock-salt-type BiS2 superconducting layer and fl…
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…
