[Pw_forum] Magnetic moment of Hydrogen

[stefano de gironcoli]

dear Rajesh,

nspin =2 (meaning two independent spin components in the density)

metallic calculation or rather define the total magnetization.
nband > 1. 2-3 should be ok. default values are usually fine.

starting_magnetization(1)=anything different from zero, in this case 
0.7-0.9 should be ok, even 1.0.

An Hydrogen isolated atom may have some issues due to the fact that one 
of the two spin channels should be completely empty and I'm not sure how 
the code deal with zero density.

maybe you can do calculations for total_magnetization 0.7, 0.8, 0.9, 
0.95, 0.99 and see where it goes.
