WitrynaI used ISMEAR = -5 and Sigma 0.05 for DOS and same Sigma value for band structure with default value of ISMEAR. Moreover, I have extended band structure on more high symmetrical points, but the result is same as shown in the attached figure. I have also varied k-points in DOS calculations, but I got the same result. 0 votes 0 thanks Witryna11 mar 2014 · ISMEAR = 2 ; SIGMA = 0.2 spin: ISPIN=2 MAGMOM = 5*1 dynamic: IBRION = 1 NSW = 100 POTIM = 0.2 K-Points 0 M on khorst-Pack 9 9 1 0 0 0 INCAR startjob; initial charge-density from overlapping atoms energy cut-off: 270 eV (default) MP-smearing (metal!) spinpolarized calculati on initial moments of 1 i on ic relaxati on …
