In the case of nscf calculations, 7.2 used to print all zeros or random non-initialised values. Now it reads the value from the density files and print it, only we are propagating this value to other processes in the wrong way. </div>

So, for older versions, use scf calculations, if you use nscf, don't use pools, or if you use pools, correct the value inside the XML by dividing it by the number of pools you have used. </div>

<b>Subject:</b> [QE-users] Possible bug in the magnetization report in xml file</div>
<div style="direction: ltr;"> </div>
</div>
<div style="font-size: 11pt;">Hello,<br>
<br>
I want to report a possible bug about the magnetization in the xml<br>
files. For an example, in the SCF output file, I am getting correct<br>
total magnetization = 1 mu_B/cell and absolute magnetization = 1.18<br>
mu_B/cell. However, in the OUTDIR/PREFIX.xml and in the<br>
OUTDIR/PREFIX/save/data-file-schema.xml - in these two files the total<br>
magnetization is given as 2 while absolute magnetization is given as 0<br>
(this is incorrect).<br>
<br>
data-file-scheme.xml:<br>
<magnetization><br>
<lsda>true</lsda><br>
<noncolin>false</noncolin><br>
<spinorbit>false</spinorbit><br>
<total>2.000000000000038E+000</total><br>
<absolute>0.000000000000000E+000</absolute><br>
</magnetization><br>
<br>
scf.out:<br>
! total energy = -4732.89719036 Ry<br>
estimated scf accuracy < 7.7E-09 Ry<br>
<br>
total magnetization = 1.00 Bohr mag/cell<br>
absolute magnetization = 1.18 Bohr mag/cell<br>
<br>
This is not an isolated case. In almost all calculations, this mismatch<br>
of magnetization between the output file and the xml files happens. I am<br>
using QE v7.4.1. This creates problem for post-processing codes such as<br>
WEST code which reads the total magnetization from the xml output to<br>
apply quasiparticle corrections and so on. I attached the output files.<br>
When I inspected my previous calculation, I noticed that this problem<br>
didn't occur in v7.2.<br>
<br>
Sincerely,<br>
