<p>Dear Quantum Espresso users,<br>
</p>
<p><br>
</p>
<p>I would like to carry out a calculation where I include spin-orbit coupling for Neodymium to examine its magnetic properties. It is my understanding that fully relativistic pseudopotentials are needed for such a calculation.<br>
</p>
<p>Unfortunately, I have not been able to find any relativistic pseudopotentials for the two atoms I am interested in (Nd, and Sm).<br>
</p>
<p>I am uncertain how to proceed because I know that the RS coupling scheme is commonly used for these atoms and I would expect the orbital contribution to be important for the calculation.<br>
</p>
<p>Finally, can spin-orbit coupling be used with LSDA? I ask this question because carrying out a spin-orbit calculation in Qunatum Espresso requires specifying noncolin=.true.<br>
</p>
<p><br>
</p>
<p>I would greatly appreciate any clarifications on this issue.<br>
<br>
</p>
<p>Thanks,<br>
</p>
<p>Adib Samin<br>
