<div dir="ltr"><div>Hi,</div><div><br></div><div></div><div>I want to compute the orbital magnetic moment at certain kpoints in the Brillouin zone using Quantum
Espresso-Wannier90 interface. What I have understood from <font style="font-family:Calibri,Helvetica,sans-serif,serif,"EmojiFont"" size="2" face="Calibri,Helvetica,sans-serif" color="black"><span dir="ltr" id="gmail-m_-5312051716234903569gmail-divtagdefaultwrapper"><a href="http://www.wannier.org/ford/sourcefile/berry.f90.html" target="_blank">http://www.wannier.org/ford/sourcefile/berry.f90.html</a></span></font> is that the quantity M_orb(k) (eg., in the kslice calculation) has to be multiplied by (-e/2hbar) if I want to compute the orbital moment at that k point. Is this correct? <br></div><div><br></div><div>Also while reproducing the example 19, I found that the net orbital magnetization of Fe has a positive value
if the starting magnetization is set at (00-1). Does that mean the spin and orbital moments are anti-parallel or there is a different sign convention. I am asking this because Ref. 17 of the user-guide reports that the spin and orbital moments are parallel. <br></div><div><div><font style="font-family:Calibri,Helvetica,sans-serif,serif,"EmojiFont"" size="2" face="Calibri,Helvetica,sans-serif" color="black"><span dir="ltr" id="gmail-m_-5312051716234903569gmail-divtagdefaultwrapper">I may be missing something.</span></font><font color="black"><font size="2"><font face="Calibri,Helvetica,sans-serif"> </font></font></font>Any comment or suggestion in this regard will be helpful for me to understand. <br></div><div>Thanks,</div><div><br></div><div></div><div>Sayantika Bhowal</div><div>Post Doctoral Research Associate</div><div>University of Missouri, Columbia, USA</div></div><div><br></div></div>
