Dear Ivan,
First at all, thanks for your suggestions, let's clarify

Both converge with SIESTA and also the Ferromagnetic calculation with
SMEAGOL.
I change MixSCF1 to TRUE and no present appreciable loose of charge. However
still without converge. I paste the tail of buffer.out and maybe can suggest
something.
Thank you!
