You did Dr. Pieper's exercise [
http://www.mail-archive.com/wien%40zeus.theochem.tuwien.ac.at/msg11090.html
]?
For example:
muB = ~5.7884*10^-5 eV/T [ http://en.wikipedia.org/wiki/Bohr_magneton ]
muB*Bext = (5.7884*10^-5 eV/T)*(10 T) = 5.7884*10^-4 eV
Likely the point is, say you plot DOS with an energy range of -5 to 5 eV
with 1 eV major increments. Probably, you are not going to see any
change in the DOS plot with a 10 T field. muB*Bext would likely need to
be on the order of about 0.1 eV (corresponding to Bext = ~1728 T) to see
any change with that energy range scale. If on the other hand the plot
of your DOS was say plotted with an energy range of -10*10^-3 eV to
10*10^-3 eV with 1*10^-3 eV increments, then the change with a 10 T
field would probably be noticeable (unless it is overwhelmed by noise in
the numerical calculation [
http://www.mail-archive.com/wien%40zeus.theochem.tuwien.ac.at/msg09466.html
]).
So you need to either change the energy scale of your plots or increase
the magnetic field value to see the effects.

Dear Dr. Martin Pieper,
Thank you for your help! For my calculation, I have ever tried
different values of magnetic field ( 0.1 T, 1T, and 10T) and all of
them have no effects on the electronic structures such as DOS, or
bandstructures e.g. So you mean I should try a even larger magnetic
field ?
Thank you again!
Best Regards,
Yanli
