<DIV><FONT face=Arial>Dear Wien users,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I kept on performing antiferromagnetic calculations and
struggling in "ghostbands" errors these days. </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>The calculation runs smoothly with no magnetism. When
taking antiferromagnetism with runafm_lapw, in the first
or after a few more iteration, such errors information always
appears:</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>QTL-B VALUE .EQ. 68.15074 in Band
of energy -3.45032 ATOM= 2
L= 3</FONT></DIV>
<DIV><FONT face=Arial>QTL-B VALUE .EQ. 327.72884 in Band of
energy -3.47500 ATOM= 3
L= 3</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I have carefully read the UG, the FAQs or the digest and
learned that this might be induced by not appropriate energy-parameters for
linearization, or not appropriate local orbitals, and or bigger
</FONT><FONT face=Arial>mixing parameter. I try to change them but the problem
is still. Most confusing to me, the ghostbands appear corresponding to L=3.
However, obviously no f electron obitals was taken into account in present
system. </FONT><FONT face=Arial></FONT></DIV>
<DIV><FONT face=Arial>Some detailed information was listed below for your
reference.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Any advice would be appreciated,</FONT></DIV>
