[QE-users] error in performing ferromagnetic LSDA+U calculation

[Tavneet Kaur]

I am trying to perform LSDA+U calculation for ferromagnetic system using
input
&system
     ibrav = 0,
     nat = 4,
    ntyp = 3,
   ecutwfc = 60,
  occupations = 'smearing'
  smearing ='marzari-vanderbilt',
  degauss = 0.004,
  starting_magnetization(1)  = 0.5,
  starting_magnetization(2)  = 0.5,
  noncolin = .TRUE.,
  lspinorb = .TRUE.,
  starting_spin_angle = .true.
  Hubbard_U(1) = 1.2585,
  Hubbard_U(2) = 1.2585,
  Hubbard_J0(1) = 0,
  Hubbard_J0(2) = 0,

 &electrons
    electron_maxstep = 1000
    diagonalization='cg'
    conv_thr = 1.0d-6
    mixing_beta = 0.3

 Cl   35.4527    Cl.rel-pz-n-kjpaw_psl.0.1.UPF

I am encountering error in band.out on using spin_component = 2,
Error in routine punch_bands (1):
     incorrect spin_component
