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 !!!--
