Analysis of Fe#

Calculation Details#

  • Magnetic calculation of bcc Fe.

Target Structure#

bcc Structure
bcc Structure (a=2.87Å)

Calculation Conditions#

The same values were used for all parameters common to AOF-DFT and KS-DFT.

Parameter Value
Pseudo-atomic orbital Fe6.0_as.pao, s1p1d1
Pseudopotential Fe_PBE26_as.vps
Functional model (AOF-DFT only) Crystal26
Energy cutoff 180 Hartree
k-point density (KS-DFT only) 3.5 point/Å-1
