  We provide accurate projected augmented wave (PAW) datasets for rare-earth
(RE) elements with some suggested Hubbard U values allowing efficient
plane-wave calculations. Solid state tests of generated datasets were performed
on rare-earth nitrides. Through density of state (DOS) and equation of state
(EoS) comparisons, generated datasets were shown to yield excellent results
comparable to highly accurate all-electron full-potential linearized augmented
plane-wave plus local orbital (FLAPW+LO) calculations. Hubbard U values for
trivalent RE ions are determined according to hybrid functional calculations.
We believe that these new and open-source PAW datasets will allow further
studies on rare-earth materials.
