<div dir="ltr"><div><p style="margin-bottom:0in"><b>Hi wien2k users </b></p><p style="margin-bottom:0in"><b>I have
been working on a full Heusler alloy Ru2TiSi. Number of valence
electrons are 24 and magnetic moment is zero. So, I performed a
calculation without spin polarization. I observed that there was a very
small DoS (0.33 /Ry)crossing at fermi level,they were due to d electron
levels of transition metals. </b></p><p style="margin-bottom:0in"><b>Then, I
performed spin polarization calculation. This time dos in spin up(0.16
/Ry) plus dos in spin down (0.17 /Ry) was equal to Dos of no spin
polarized calculation. However, magnetic moment was equal to 0.00001 per
unit cell.</b></p><p style="margin-bottom:0in"><b>I then applied U for both TM, the result was MM=0.0000. Spin up and spin down looks similar with energy gap of 0.17eV.</b></p><p style="margin-bottom:0in"><b>Now,
I wish to try GGA+U. My question though: "Is it possible to do GGA+U in
no spin polarization or could I consider that that the above material
in GGA+U is a semi conductor?" </b></p><p style="margin-bottom:0in"><b>Can some one help me clarify this?</b></p><p style="margin-bottom:0in"><strong>Regards</strong></p></div><br clear="all"><br>-- <br><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">Thanks and regards<br><br>Krishnaveni Parthasarathy<br>8939675012</div></div>
