<div>Dear All ;</div>
<div> </div>
<div> I have two questions : </div>
<div> </div>
<div> What the meaning of EFG ? I think that this parameter is a tensor but the result of wien2k is a number !</div>
<div> </div>
<div> How can we find that the ground state of a system is ferro or antiferro ?</div>
<div> for example Etot can help us to find that which structure is the best . Is there any parameter to help us for finding the ground state (ferro or antiferro) ?</div>
<div> </div>
<div>Thanks for your attention </div>
