TLDR
In this paper, the electronic bandstructures of rare earth metal Praseodymium (Pr) have been calculated for a wide range of static pressures using RAPW method and the density of states and Fermi surface cross sections on the principal planes corresponding to various pressures are obtained.Abstract:
The electronic bandstructures of rare earth metal Praseodymium (Pr) have been calculated for a wide range of static pressures using RAPW method. The density of states and Fermi surface cross sections on the principal planes corresponding to various pressures are obtained. It is seen that, there is, 4f shell breakdown in Pr under pressure and formation of 4f bands. The calculation of the superconducting transition temperaturesT

corresponding to various pressures shows that Pr may become a high pressure superconductor like Cerium eventhough it is not observed experimentally to be a superconductor because of its magnetic character at normal pressure.read more

The electronic structure of gadolinium grown on Mo(112)
TL;DR: The electronic structure of thin and ultra-thin and thin films of Gd grown on a corrugated Mo(112) surface is described in this paper, and the effective mass of this interface state was determined to be, in both orthogonal directions along the nearly square reduced Brillouin zone.

Chapter 159 Surface magnetism of the lanthanides
TL;DR: In this article, the surface magnetism of the lanthanides is discussed and compared to the bulk magnetic and electronic structure of lanthanide metals. But the comparison between the bulk and the surface can be made more readily.

Transition temperature of strong-coupled superconductors.
TL;DR: In this paper, the superconducting transition temperature is calculated as a function of the electron-phonon and electron-electron coupling constants within the framework of strong coupling theory.

The α-γ transition in cerium is a Mott transition
TL;DR: In this article, it was shown that the intra-atomic interaction in cerium is considerably smaller than seems to have been believed in the past, and it is argued that in metallic cerium, U is only of the order of a few electron volts.

TL;DR: The results of self-consistent bandstructure calculations and the measured Debye temperatures are used in conjunction with the theory of Gaspari and Gyorffy to determine the electron-phonon interaction and the massenhancement factor for 32 metals with $Z = 1$ to $Z=49$ as mentioned in this paper.
