The value of RMT should not affect the type of result you get (i.e. whether you find a magnetic or nonmagnetic solution). Small changes in RMT will changes to some extent the value of the spin moment reported in :MMIxxx, because the latter is the spin moment *within* the muffin tin sphere. However, this is only an apparent change. Roughly spoken, you get the same charge and spin densities, irrespective of the value of RMT. Only the portion of the total spin moment (:MMTOT) which you assign to a particular atom (:MMIxxx) is different. Stefaan
