]?<br>
<br>
For example:<br>
<br>
muB = <span class="nowrap">~5.7884*10^-5 eV/T [
<a class="moz-txt-link-freetext" href="http://en.wikipedia.org/wiki/Bohr_magneton">http://en.wikipedia.org/wiki/Bohr_magneton</a> ]<span
style="margin-right: 0.15em; margin-left: 0.25em;"></span></span><br>
<br>
muB*Bext = (<span class="nowrap">5.7884*10^-5 eV/T</span>)*(10 T)
= <span class="nowrap">5.7884*10^-4 eV</span><br>
<br>
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 [

]).<br>
<br>
So you need to either change the energy scale of your plots or
increase the magnetic field value to see the effects.<br>

<div>Dear Dr. Martin Pieper,</div>
<div> 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 ?</div>
<div> Thank you again!</div>
<div>Best Regards,</div>
