[Wien] Exchange interaction parameters

[Victor Shaposhnikov]

Dear WIEN users,

Does  anybody  know  how to calculate the exchange interaction between
two  magnetic  atoms  in  solid?  Or  may  be  this information can be
extracted  from  some  of  WIEN  output  files?  Exchange  interaction
parameters can be used, for example, to estimate the Curie temperature
of ferromagnetic material in the mean-field approximation.

Best regards,
