<div>Dear users,</div>
<div> </div>
<div> </div>
<div>I am really wondering if we have to "relax" structure everytime when calculating magnetic materials.</div>
<div>When relaxed, the magnetic properties, especially K value, become too far from experimental data; K value calculated from not relaxed structure is also far from the experimental one.</div>
<div> </div>
<div>I tried force theorem as well, but that is still far from the experimental data too. </div>
<div> </div>
<div>Everytime my calculated K value is reversed.</div>
<div>For example, energies for <001> and <100> are compared and used to calculate K. </div>
<div>But I do not understand why the energy for <100> is lower than that of <001>.</div>
<div>Experimentally, <001> is stable for MnAl.</div>
<div> </div>
<div> </div>
<div>And another qeustion is about RMT.</div>
<div>Is it okay to change RMT to fit experimental data?</div>
<div>I tried several times to fit experimental one, but still question myself if that is okay.</div>
