Laurence, you are right, it will save a lot of time, but this is not related to the original question; why the up and dn DOS are very similar.
I think that it is because that the total mm is very small 1.57 for a system with 16x7 atoms. Pablo ________________________________ Sorry, but I will disagree: set the O to non magnetic. It will save a lot of time. Also, I suggest some care with +U for f's. At least for the 4f +U over-localizes them.

The behaviour of the magnetic moments of alloys is very often in accordance with the so called Slater Pauling rule that is, the total moment depends on the number of valence electrons and the individual moments are adjusted to result in the correct total moment. For localized moment systems it is caused by a trapping of the Fermi energy in a minimum of the density of states for minority (or majority) electrons. Maybe this explains your observation. It's not a miracle, it's physics. Ciao Gerhard DEEP THOUGHT in D.

Details are important. Once I had a study with an idea of the magnetic moment dependence on the environment. You can see result for a system with a ferromagnetic and a nonmagnetic elements.
