Dear B. SanthiBhushan,
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.

Subject: [Pw_forum] starting magnetization in nitrogen doped graphene
Dear Experts,
I am completely new to spin polarized calculations using QE.
I am trying to simulate nitrogen doped graphene (image attached below)
considering spin polarization. I have got the below two questions.
I have set nspin=2.
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) ?
Or mentioning starting magnetization for atomic type carbon is enough (like
starting_magnetizaiton(1)=0.5) ?
Q2) How to decide the value of starting magnetization ? is it random ? 0.5
considered in my case is enough or not ?
I thank you very much for your precious time and knowledge.
Sincerely,
B. SanthiBhushan,
