<div>Dear Wien2k Users,</div>
<div> </div>
<div>I am trying to calculate the electronic structure of Heusler alloy Fe2CrSn using Wien2k. It is supposed to exist in L2/1 structure (space group 225) with following positions:</div>
<div>Fe: 0.25 0.25 0.25</div>
<div>Fe: 0.75 0.75 0.75</div>
<div>Cr: 0.5 0.5 0.5</div>
<div>Sn: 0.0 0.0 0.0</div>
<div> </div>
<div>When the positions are changed as follows:</div>
<div>Fe: 0.0 0.0 0.0</div>
<div>Fe: 0.5 0.5 0.5</div>
<div>Cr: 0.25 0.25 0.25
<div>Sn: 0.75 0.75 0.75</div>
<div> </div>
<div>then the Wien shows space group 216 and magnetic properties are totally changed.</div>
<div> </div>
<div>Is it right and what is the excact structure for Fe2CrSn?</div>
<div> </div>
<div>Please help me.</div>
<div> </div>
<div>Thanks in advance,</div></div>
