[Wien] exchange interaction J

[marziye foroughpour]

Dear wien2k users,

   I want to estimate the Curie temperature within Mean-field theory.
 You know that for calculation this temperature I need exchange
interaction in   Heisenberg Hamiltonian and with J,j= ~-~) d, Im
Trt.{A,i;JAji~' }. ,
I'd like to know How can I calculate exchange interaction (J) by Wien2k  for
a
system with Half-metallic ferromagnetic property If it's
possible??
I heard about  connection between J and difference energy s of ferromagnetic
and paramagnetic structure, what  ratio is between J and those energie
