Nota bene: an vacuum induction field of approximately 0.23 T will give about 
10^-6 Ry/mu_B (1 microRydberg per Bohr magneton)

My guess is, at 0.1 T nothing in the calculation will change at all and from 
experience I can tell that this is true.
 I am not even sure whether this is enough to force a -- say metastable --  
"spin polarized" solution when starting from  non-polarized densities.

"0.1."    is not a valid number (the program does not know what to do
with the 2 dots.)

PS: I'd recommend a much larger field. And be aware that the action
acting on the orbital moment is only a crude onsite-approximation.
