Structure–property relationships of iron arsenide superconductors
Iron based superconductors sent material scientists into a renewed excitement reminiscent of the time when the first high-Tc superconductors were discovered 25 years ago. This feature article reviews relationships between structural chemistry and magnetic as well as superconducting properties of iron arsenide compounds, which are outstandingly rich and uniquely coupled. Particular attention is ...
متن کامل(p, p) electronic order in iron arsenide superconductors
The distribution of valence electrons in metals usually follows the symmetry of the underlying ionic lattice. Modulations of this distribution often occur when those electrons are not stable with respect to a new electronic order, such as spin or charge density waves. Electron density waves have been observed in many families of superconductors, and are often considered to be essential for supe...
متن کاملGap structure in the electron-doped iron–arsenide superconductor Ba(Fe0.92Co0.08)2As2: low-temperature specific heat study
In this paper, we report the field and temperature dependence of low-temperature specific heat down to 400mK and in magnetic fields up to 9 T of the electron-doped Ba(Fe0.92Co0.08)2As2 superconductor. Using the phonon specific heat obtained from pure BaFe2As2, we found a normal state Sommerfeld coefficient of 18mJmolK−2 and a condensation energy of 1.27 Jmol. The temperature dependence of elect...
متن کاملBogoliubov angle in electron-doped cuprate superconductors
Within the framework of the kinetic energy driven superconducting mechanism, the momentum dependence of the Bogoliubov angle in the electron-doped cuprate superconductors is studied. By calculation of the ratio of the low energy quasiparticle spectra at positive and negative energies, it is shown that the Bogoliubov angle increases monotonically across the Fermi crossing point, suggesting a con...
