Features of the electronic structure of the ternary superconductors RRh4B4 (R= Y, Lu)
GE Grechnev, AV Logosha, AS Panfilov… - Low Temperature …, 2016 - pubs.aip.org
The electronic structure and a number of thermodynamic characteristics of the ternary RRh 4
B 4 (R= Y, Lu) systems of superconductors in the normal phase are calculated from first
principles. The electronic states and interactions responsible for the superconducting and
magnetic properties of these systems are analyzed. It is found that the Fermi level in the
compounds YRh 4 B 4 and LuRh 4 B 4 is immediately adjacent to a peak in the density of
electronic states and about 1 eV above a pseudogap in the electronic spectrum. The …
