<p>Someone else may know differently, but as far as I know, WIEN2k
has no function for calculating MR (magnetoresistance). <br>
</p>
<p>I don't know the details of what your are trying to do exactly,
but it may be that WIEN2k's magnetic field doesn't do what you
think it does.</p>
<p>Refer to the previous posts:</p>

<p>For example a VSM with Magneto Resistance option can only apply
up to 3.5 T [ <a class="moz-txt-link-freetext" href="http://www.microsense.net/products-vsm.htm">http://www.microsense.net/products-vsm.htm</a> ]. Some
of the best electromagnets in the world cannot apply too much
higher magnetic fields than that. In the above post, at least a
10 T magnetic field has to be applied to even see an effect.
However, I don't know how to properly explain that. My guess is
that might be because WIEN2k's magnetic field is an atomic local
field instead of a micro/macro uniform field.</p>
<p>Do you maybe need a spin-polarized current in a spin-torque based
micromagnetic simulator like oommf [ <a class="moz-txt-link-freetext" href="https://math.nist.gov/oommf/">https://math.nist.gov/oommf/</a>
, <a class="moz-txt-link-freetext" href="http://layer.uci.agh.edu.pl/M.Frankowski/download.html">http://layer.uci.agh.edu.pl/M.Frankowski/download.html</a> ], LLG
Micromagnetic Simulator [

], or VAMPIRE [ <a class="moz-txt-link-freetext" href="http://vampire.york.ac.uk/research/">http://vampire.york.ac.uk/research/</a> ]?</p>
<p>Or are you trying to calculate magnetic anisotropy energy (MAE) [
<a class="moz-txt-link-freetext" href="https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg09408.html">https://www.mail-archive.com/wien@zeus.theochem.tuwien.ac.at/msg09408.html</a>
]? </p>
<p>I never figured out how to do it, but tunneling current is a
function of density of states, fermi functions, and tunneling
probability [ <a class="moz-txt-link-freetext" href="http://dx.doi.org/10.9756/BIJPSIC.3129">http://dx.doi.org/10.9756/BIJPSIC.3129</a> ]. So I
thought there might be a slight possibility to extract data from
WIEN2k and post calculate that.<br>
</p>
<p>Hope that can help and good luck.<br>

<div>I want to calculate anisotropy in magnetoresistance. I want
to to apply both magnetic field and current at same time to a
system. In wien2k through inorb<br>

I can apply magnetic field, but how to give current at the same
time. <br clear="all">
