[Pw_forum] Local magnetic moment

[Duy Le]

If an electron has negative Sz, its magnetic moment would be negative. Sz of
majority spin electrons in your system is negative.
Just flip the molecule (system) 180o (change direction of z coordinate) you
will get positive magnetic moments (but you don't have to).
