```Dear all

I have doubt in calculating magnetic moment.  Found few communications
on this topic but no where a clear answer is found. If i want to find
out the magnetic moment of an atom in a system, how am i going to get
it. After doing the pdos calculations the *.pdos.out file is obtined
which contains the Lowdin charges. For example say the following is the
portion of the Lowdin charges obtained.

Lowdin Charges:
Atom #   5: total charge =   4.5686, s, p, d, f =   0.2749   0.8321  3.4616
spin up      =   2.9945, s, p, d, f =   0.1449   0.4269  2.4227
spin down    =   1.5742, s, p, d, f =   0.1300   0.4052  1.0390
polarization =   1.4203, s, p, d, f =   0.0149   0.0217  1.3837

How do i get the magnetic moment for the atom 5 from this? The total magnetization
is reflected in the *.scf.out file. Is there any formula regarding this?
