Re: [Wien] Interstitial magnetic moment
Free electrons do not contribute to the magnetic moment, this magnetic moment is due to localized electrons around atoms, but go out of the MT sphere.

[Wien] Interstitial magnetic moment
Dear WIEN2k users; does a relatively large value (1muB-2muB) of the interstitial magnetic moment mean a metallic behavior of the material as a result of the presence of electrons in this region? if it is no, what is the origin of this value? ___ Wien mailing list Wien@zeus.theochem.tuwien.ac.at http://zeus.theochem.tuwien.ac.at/mailman/listinfo/wien SEARCH the MAILING-LIST at: http://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/index.html
Re: [Wien] interstitial magnetic moment in AFM calculations
Seems your case.inclmcopy file is NOT correct. In some cases the opposite can happen, namely that runsp yields a ferrimagnetic state, but runafm must yield :MMTOT=0 (when the inclmcopy file is correct). However, I do not really understand your messages about MMI001=3 (it is "never" integer inside the atomic spheres) and you did not report :MMTOT.

Re: [Wien] interstitial magnetic moment
The interstitial is the set of points of space which are not in any of the atomic spheres. So, the spin interstitial magnetic moment (:MMINT) is the difference between the number of spin-up and spin-down electrons in the interstitial. F.
