<br>Dear Padmaja,<br><br>if you give zero starting_magnetization to all the atoms in your system you will obtain a non magnetic solution.<br>The code won't be able to evolve any finite magnetization on any atom.<br>what you should do is to give finite magnetization to atoms, some positive some negative, so that an antiferromagnetic<br>
solution can in principle appear. The AFM solution could be not unique, however, so different initial configurations<br>could correspond to different final results.<br><br>hope this helps,<br><br>Matteo<br><br><br><br><div class="gmail_quote">

Dear All<br><br>I have a doubt in the input for FM and AFM calculations. I am calculating for a compound semiconductor. If i have three different elements in the sample. I want to proceed with FM calculations then in the input I give nspin =2 and some positive value for starting magnetization for each element in the sample. Again for AFM calculations I give the input as nspin =2 and zero starting magnetization for all the three elements. Is this correct? <br>
<br>Thanking in advance<br>regards<br>Padmaja Patnaik<br>
