Hello,
I have replicated some band structure (and other) calculations for a
noncollinear antiferromagnet that I previously completed with VASP. I am
interested in figuring out how to plot the magnetization density in the
unit cell using QE. With VASP, the CHGCAR file contains data in the format
...
rho+ rho- mx my mz
...
so it is fairly simple to do. However, I am unable to reproduce this in
QE. From my reading of the pp.x inputs page, I see that there is, for
the "plot_num"
variable, two seemingly relevant options:
plot_num=7 : where I then have to specify the spin_component for
charge, mx, my, mz. I am unsure what to pass here for "kpoint(i)" and
"kband(i)". I just want the total magnetization density in the unit
cell, so presumably this is the sum of the band magnetization density
weighted by occupancy? (I am not sure about this)
plot_num=13: when I pass spin_component=1 (or 2, or 3) I get a large
text file full of zeroes.
I notice in the output directory, there are three files called
"magnetization.x.dat" (and y, and z). Does this already contain the
relevant info? What are these files? They seem to be in binary and I
have tried importing them using various encodings but it is all
gibberish thus far.
I would greatly appreciate any guidance in this matter. Thank you.
