Dear Dr. Lorenzo,
sorry for the previous incomplete mail.

I have done two LSDA calculation with total_magnetization and without it
using pbe0. In case of GGA that total magnetization value remain fixed
after scf minimization where as in pbe0 as I told you earlier it is not
writing
total magnetzation but if I just  add magnetic moment at each site which is
equivalent to total_magnetization, is different from that value that I have
provided in input parameter, what does it mean actually, can you please
help me in this regard.

Thanking You,
Sincerely,
Rita Maji
