Dear Prof. Blaha and Wien2K users,<br><br> I am working on single Fe impurity in some sp metals.<br>I am getting Orbital moment almost zero in GGA+U calculation<br>always, whereas Orbital polarization gives L~ 2. Is it necessary<br>
to do orbital polarization for single impurity in sp metals ? The orbital<br>moment of Fe in transition metal hosts vanishes due to crystal field<br>effects. My question is where one should go for orbital polarization calculation especially ?<br>
<br><br>with sincere regards<br>susanta<br><br><br>
