Dear all,
i want to study a binary alloy FeRh, this system have two magnetic 
configuration one ferromagnetic
and one antiferromagnetic. The structure is the same (CsCl)
i begin with the ferromagnetic so i set SpinPolarized to true, all it's fine.
now to do calculations for the antiferromagnetic configuration i use the same 
*.fdf in which i set 
these parameters:
===================================
SpinPolarized           T
FixSpin                 T
DM.InitSpinAF           T
TotalSpin               0.0
===================================
after calculation is done the total spin polarization is not 0!!!
and the density of states is not symmetric!!
siesta: Total spin polarization (Qup-Qdown) =    1.933606
how can i fix that?
cheers

Subject: [SIESTA-L] the test results are different with the references in 
siesta-trunk-458

Hi i test the  ~/siesta-trunk-458/Obj/Tests/batio3, and the part of batio3.out 
is

so not only the data are different, the  computational ways are different, 
there i am wondering the reference out file is generated by the same input with 
the test file?


thanks very much !!!--
