Hi,<br><br>I am new to PWScf and i am working on ZnO doped with Nitrogen .I have replaced 1 Oxygen by 1 Nitrogen per unit cell and have used 2*2*2 ZnO supercell i.e 8*(ZnO)-O+N=143 total no. of electrons .It means our system has an odd no. of electrons and i have given ispin=2 but i m confused how to specify the tot-magnetization value.<br>
<br>secondly ,I want to know whether one should use spin polarized calculation for geometry optimizations/relaxation for the above system.If needed, should I paste my input file also?<br><br>sincerely,<br>Miss Kajal<br>
