Thanks Sir,
but i am asking about that matrices which appears in AFM calculation. how i define that matrices symmetry operation (rotation + translation vector)  which converts spin up into dn????????????????
what is the method to find the proper symetry operation matrices for any case?
thanks and regards
Arqum Hashmi

Change the equivalent atoms to inequivalent by changing it
as Cr1 and Cr2 in the supercell struct file. Copy the supercell struct file
into the struct file. Then define the spins of atoms in instgen_lapw.

Dear users
i am new user of wien2k.i want to calculate AFM calculation.i read already
about BCC Cr but that is very simple case. But i dn't know how to find the
proper symetry operation matrices for any case?  
My structure
is Rohmbohedral and when i made supercell now it is hexagonal then now how can
i give proper symmetry operation which converts spin up into dn????
Please guide me about this or tell me about any literature which explains symmetry
operation (rotation + translation vector) which transforms the spin-up into the
spin-dn atom.  
i will be
very thankful to you.
Best Regards
