Dear WIEN2k users,<br> <br> I am trying to use the SKEAF programme to calculate the de Haas–van Alphen<br>frequencies from the band energy. I tried to explore the dHvA frequency. But I have<br>some doubt. <br>
<br>My system is cubic system.<br><br>What actually I did:<br><br>
1.Reading data from the bxsf file.<br><br>2. Number of interpolated k-points per single new cell side : 100<br><br>3. H-vector: a<br><br>4. Minimum allowed extremal Fermi surface : 0 (to allow all extremal frequencies)<br>
<br>5. set the parameters used for determining which orbits are multiple copies of one another and<br>
therefore should be averaged together: 0.01 (for default = 1%)<br><br>6. Maximum distance (fraction of RUC side length) between average coordinates for orbit averaging:<br>0.05 for default = 5% of RUC side lengths<br><br>
7. Allow extremal orbits located near super-cell walls: n (no)<br>
<br>After this I got the output as below :<br>But I did not understand why it is repeating the results, and what is my actual<br>frequency ?<br><br>Can any one explain more details about this ?<br>Previously I sent the same but I did not get any reply still.<br>
This time I am expecting some response.<br><br>Thanking you<br clear="all"><br>-- <br>Swetarekha Ram,<br>Research Scholar,<br>Dept. of Physics,<br>IIT Hyderabad.<br><br><br>
