<div dir="ltr"><div><div><div><div><div><div>Dear all,<br><br></div>I want to indicate
the magnetic ground state of a bulk crystal which is not known
experimentally, I know I have to set up different magnetic ordering
which might be many Antiferromagnetic orderings(AF1, AF2, AF3, ...) and
one Ferro ..., and in the end just comparing their SCF energy to find
the lowest one.<br>My first question is:<br>Should the orders in a
specific ordering for example AF2, must be fixed? if not, do not you
think that all different orderings converge finally to the same state?
as these orders we indicate in the beginning are just a initial ordering
and they are probably allowed to change as SCF approaches to the
convergence.<br><br></div>The second question is:<br></div>I was
wondering if different orders (AF1, AF2, ... , Ferro ...), must be
optimized and minimized first? and then run the usual SCF for every of
them. Because as I know the magnetic state is a effective parameter on
the final optimized structure. If the per-optimized is not that
necessary, then which structure must be considered as platform to setup
different magnetic ordering on it, maybe optimized one
none-magnetically.<br><br></div>I hope I could clearly asked my question and any comment would be highly appreciated.<br><br></div>Best regards,<br><br></div>Alex</div>
