Universal scaling behavior of the upper critical field in strained FeSe0.7Te0.3 thin films

Feifei Yuan, Vadim Grinenko, Kazumasa Iida +12

Revealing the universal behaviors of iron-based superconductors (FBS) is important to elucidate the microscopic theory of superconductivity. In this work, we investigate the effect…

The influence of the in-plane lattice constant on the superconducting transition temperature of FeSe0.7Te0.3 thin films

Feifei Yuan, Kazumasa Iida, Vadim Grinenko +12

Epitaxial Fe(Se,Te) thin films were prepared by pulsed laser deposition on (La0.18Sr0.82)(Al0.59Ta0.41)O3 (LSAT), CaF2-buffered LSAT and bare CaF2 substrates, which exhibit an almo…

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…

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…
