<div>Dear B. SanthiBhushan,</div><div><br></div><div>Yes, Simply set initial magnetic moments by starting_magnetization(1) and starting_magnetizaiton(2) for carbon and nitrogen. I guess 0.1 is sufficient for any doping configurations in your case. </div><div><br></div><div>Best</div><div><br></div><div>Jibiao Li</div><div><div><br></div><div><br></div><div style="font-size: 12px;font-family: Arial Narrow;padding:2px 0 2px 0;">------------------ Original ------------------</div><div style="font-size: 12px;background:#efefef;padding:8px;"><div><b>From: </b> "B S Bhushan";<ecebhushan@gmail.com>;</div><div><b>Date: </b> Thu, Oct 5, 2017 08:03 PM</div><div><b>To: </b> "PWSCF Forum"<pw_forum@pwscf.org>;<wbr></div><div></div><div><b>Subject: </b> [Pw_forum] starting magnetization in nitrogen doped graphene</div></div><div><br></div><div dir="ltr"><div><div><div><div><div><div><div><div><div><div><div>Dear Experts,<br><br></div>I am completely new to spin polarized calculations using QE.<br><br></div>I
am trying to simulate nitrogen doped graphene (image attached below)
considering spin polarization. I have got the below two questions.<br><br></div>I have set nspin=2.<br><br></div>Q1)
Now, should I have to set starting magnetization for both carbon and
nitrogen atomic types (like starting_magnetization(1)=0.5,
starting_magnetizaiton(2)=0.5) ?<br><br></div>Or mentioning starting magnetization for atomic type carbon is enough (like starting_magnetizaiton(1)=0.5) ?<br><br></div>Q2) How to decide the value of starting magnetization ? is it random ? 0.5 considered in my case is enough or not ?<br><br></div>I thank you very much for your precious time and knowledge.<br><br><br></div>Sincerely,<br></div>B.
