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