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.
