Dear Forum,<br>
<br>
I tried to use the ph code in order to compute Born effective
charges for a spin-polarized system.<br>
The results I've obtained from the "zue" and the "zeu" methods are
different.<br>
<br>
The values for the Fe atom in one case are positive and in the other
are negative.<br>
I've used the version of the code from the cvs repository<br>
(which was working properly for a non-polarized system.)<br>
<br>
Any suggestion?<br>
Attached the output of the two calculations and of the pwscf run.<br>
<br>
Thank you and best regards,<br>
Davide<br>
