[Wien] Magnetic moments!!

[zufengxia at sohu.com]

Dear Wien users,
    I am calculating an ferromagnetic system including metal-ion Ni, the magnetic moments of Ni are 2.21 according experimental data, while my results show it is only 1.59, and the parameter Rmt=2.0 for Ni,which has already reach the maximum.
  How to increase the magnetic moments of Ni? What parameters should be changed ? Would you please give me some suggestions?  

 best regards
