[Pw_forum] convergence of local magnetic moment

2016-10-31 Thread ilahi asma
Dear QE users, I try to calculate the local magnetic moment of LiF structure 
with Li vacancy, I found a value of 1.00µb but after relaxation this value 
augmented until 1.33µb.I can't understand the reason of this increase. can 
someone help me please.

 Hello all,I'm studing The LiF(001) fcc structure.how to choose the lattice 
parameter?? is it the same of the bulk  
Best regards.

Hello all,I'm studing The LiF(001) fcc structure. I try to stabilize my system 
but my problem is always when I run a job to calculate the K-point 
{(441),(661),(881)} convergence, this  calcul does  not converge.In the scf 
output, I always found this sentence "convergence NOT achived after 100 
iterations : stoping"can you help me ???
Best regards.
