Hi Jaroslav, if you check only case.jointup it has possibly only half the value because the other half is supposed to be in case.jointdn (with SO they should be the same) Did you try to copy case.jointup to case.jointdn (or run in addition everything for dn) and then addjoint then the factor 2

First, as Gavin told, your convergence criteria are too bad to decide about your magnetic moments just try to improve them in steps say up to ec 10^-6 cc 10^-3 and see what happens with the moments (that was why I asked fror it) however be sure you have enough k-points I assume you used the
