Dear Prof. Stefan Cottenier and wien2k users,<br><br>My question is regarding the spin structure for a SDW calculation. As far<br>my knowledge, the unit cell need to be extended in a particular direction,<br>equivalent or greater than the wave vector, i.e. in case of Cr, the unit cell<br>
length has to be 50 A, which is the magnitude of the wave vector. But how to set<br>up the spin configuration ? Whether the alternate atoms should be + -+ - or half of the<br>length is + and another half - ? Another thing is, symmetry may not allow to the desired<br>
spin states while setting up the case.<br> <br> I don't think question has been posted earlier, user guide is also silent about this. Any suggestion <br>in this regard will be useful. Please provide some references if possible.<br>
<br>with regards<br>susanta<br><br> <br>
