Many thanks for your guidance. Actually my system has magnetic (2) and
non-magnetic (3) species. As B_ext. means we are apply magnetic field
on the whole system then why do we need to select natorb = 2 ?
Bext is applied to the iatoms (i.e., in atomic spheres) that you specify
in case.inorb. The program searches for file case.vorbup, if it finds
it, Bext energy is add to Vxc in atomic spheres and in interstitial
region [ http://www.wien2k.at/reg_user/textbooks/orbital_potentials.pdf
(section "4.1 LAPW0 package" on page 6)].
Secondly could you please clarify to me about "adjusting the
"direction of Bext in terms of lattice vectors" line in case.inorb.".
Any example please or guidance that how to make it.
y = x*tan(theta) = 1*tan(32 degrees) = 0.62487 [
Consider a cubic lattice with the "direction of Bext in terms of lattice
vectors" set to:
1 0.62487 0
Calculation of the angle between vector (1,0,0) and vector (1,0.62487,0)
octave:1> a=[1 0 0]
1 0 0
octave:2> b=[1 0.62487 0]
1.00000 0.62487 0.00000
angle_rad = 0.55851
angle_deg = 32.000
This gives an angle of 32 degrees with respect to the (100) axis.
