Kamihara and coworkers' report of superconductivity at T c= 26 K in fluorine-doped
LaFeAsO inspired a worldwide effort to understand the nature of the superconductivity in this …

For the first time in the world, we succeeded in synthesizing the room-temperature
superconductor ($ T_c\ge 400$ K, 127$^\circ $ C) working at ambient pressure with a …

The discovery of superconductivity at relatively higher temperatures in a non-cuprate
system, LnFeAsO 1− x F x (Ln= lanthanides) has created tremendous activity among the …

We study the effect of the lattice structure on the spin-fluctuation-mediated superconductivity
in the iron pnictides adopting the five-band models of several virtual lattice structures of …

We report bulk superconductivity induced by an isovalent doping of phosphorus in BaFe 2
(As 1− x P x) 2. The P-for-As substitution results in shrinkage of the lattice, especially for the …

The superconductor Sr 4 V 2 O 6 Fe 2 As 2 with transition temperature at 37.2 K was
successfully fabricated. It has a layered structure with the space group of p 4/nmm and with …

The temperature-dependent electrical resistivity of single-crystalline SrFe 2 As 2 and BaFe 2
As 2 has been measured in a liquid-medium modified Bridgman anvil cell for pressures in …

Single-crystal neutron and high-energy x-ray diffraction measurements have identified the
phase lines corresponding to transitions among the ambient-pressure paramagnetic …

We report a strategy to induce superconductivity in the BiS 2-based compound LaOBiS 2.
Instead of substituting F for O, we increase the charge-carrier density (electron dope) via …

The electronic structure of the Fe-based superconductors is discussed, mainly from the point
of view of first principles calculations in relation to experimental data. Comparisons and …
