Iron-basedsuperconductorsare interesting due to their intrinsicmagnetism, which often precedessuperconductivity. Since 2008, advances have attempted to resolve this apparent but non-obvious link. This has resulted in growing evidence that iron based compounds, especially those containing Fe-X (X = Group...
In contrast, if the same sign of the superconducting gap is taken for the two bands, the simulated band structure (Fig. 2i) deviates far from the measured result (Fig. 2d). The observation of the unusual band structures in the superconducting state and their quantitative understanding based ...
High-temperature superconductors placed in the center of our research are the type-II superconductors. Therefore, their properties and superconductivity mechanisms are considered in more detail. The term type-II superconductors was first introduced by Abrikosov in his classical paper [4], where he ...

For example, in the work of Hutcheon et al. the Tc of hydrides for elements in the second and third groups are also relatively high. However, some notable discrepancies exist in their ML predictions, such as the underestimated Tc of about 100 K for Y, La, and Th hydrides, even when ...
The conference website was very comprehensive; for the fi rst time there was an app with the conference program and useful information that could be downloaded and used on mobile devices; there were no proceedings so that the scientists are now able to submit their highquality papers to ...

Contrary to nonmetallic systems such as MgB2 or cuprates, thin and ultrathin films of NbN and TaN can be produced of very high quality, for example, by reactive dc-magneton sputtering [57, 58]. They are of particular interest due to their high critical temperature that makes them suited ...
(Received 8 March 2012; published 30 May 2012) Although iron-based superconductors are multiorbital systems with complicated band structures, we demonstrate that the low-energy physics which is responsible for their high-Tc superconductivity is essentially governed by an effective two-orbital Hamiltonian...
(DFT) calculations show, besides the Ni\({d}_{{x}^{2}-{y}^{2}}\)orbital, additional bands around the Fermi levelEF15,20,21,35that are of predominant Nd-5dcharacter and overlap with the former. Note that the Nd-5dbands in Fig.1a extend belowEFdespite their centre of gravity ...
