Dear Giuseppe,
   I do not want to converge to AFM ground state. As per the literature the 
ground state is FM. My main problem is not getting differences in spin up and 
spin down bands and dos.

Best,
Eesha

Dear Eesha

> Do I need to provide starting magnetization for both the atoms?

Yes, you do if you want to converge to an antiferromagnetic ground
state. You should provide two different starting magnetizations using
fake atomic labels, e.g, Cr1 and Cr2, in a range between 0 (no
magnetization) and 1 (all d electrons unpaired).
