Fully relativistic pseudopotentials

Fully relativistic pseudopotentials generated by
the MBK (PRB 47, 6728 (1993)) scheme within LDA (CA13) and GGA (PBE13) which contain
a partial core correction and fully relativistic effects including spin-orbit coupling.

Pseudo-atomic orbitals

The number below the symbol means a cutoff radius (a.u.) of the confinement
potential. These file includes fifteen radial parts for each angular
momentum quantum number l (=0,1,2,3,4). The basis functions were generated by variationally
optimizing the corresponding primitive basis functions in the single atom and the FCC bulk.
The input files used for the orbital optimization can be found at
Dy_opt.dat
and
Dyfcc_opt.dat.
Since Dy_CA13.vps and Dy_PBE13.vps include the 4f, 5s, 5p, and 6s states (20 electrons)
as the valence states, the minimal basis set is Dy*.*-s2p1f1.
Our recommendation for the choice of cutoff radius of basis functions is that
Dy8.0.pao is enough for bulks, but Dy10.0.pao or Dy12.0.pao is preferable
for molecular systems.

Benchmark calculations by the PBE13 pseudopotential

**(1) Calculations of the band dispersion in the fcc structure,**
where the non-spin polarized collinear calculation with the lattice constant of 4.990 Ang.
was performed using Dy_PBE13.vps and Dy8.0-s3p3d3f2, and the origin of the energy
is taken to be the Fermi level.
The input file used for the OpenMX calculations can be found at
Dyfcc-Band.dat.
For comparison the result by the Wien2k code is also shown, where
the calculation was performed by default setting in the Ver. 9.1 of Wien2k
except for the use of R_{MT} x K_{MAX} of 12.
