The electronic structure of the Na $_{x}$ CoO $_{2}$ surface

D. Pillay, M. D. Johannes, I. I. Mazin

The idea that surface effects may play an important role in suppressing $e_{g}^{'}$ Fermi surface pockets on Na $_{x}$ CoO $_{2}$ $(0.333 \leq x \leq 0.75)$ has been frequently proposed to expla…

The challenge of unravelling magnetic properties in LaFeAsO

I. I. Mazin, M. D. Johannes, L. Boeri +2

First principles calculations of magnetic and, to a lesser extent, electronic properties of the novel LaFeAsO-based superconductors show substantial apparent controversy, as oppose…

The origin of a $_{1 g}$ and e $_{g}$ ' orderings in Na $_{x}$ CoO $_{2}$

D. Pillay, M. D. Johannes, I. I. Mazin +1

It has often been suggested that correlation effects suppress the small e_g' Fermi surface pockets of NaxCoO_2 that are predicted by LDA, but absent in ARPES measurements. It appea…
