[Pw_forum] magnetic moment

[Sakhrawi Taoufek]

i read that the value of starting magnetization is used to brake the up/dw symmetry  in the charge density but when i fix all parameters and i change the values of starting magnetization the value of total magnetization and 

the magnetic moment of each atom changes. U can't understand the relation between starting magnetization, total magnetization and the local magnetic moment
there is any adea??

Bearing in mind that partitioning charge among atoms is arbitrary, the 
code projwfc.x will do that job by projecting the charge on atomic 
wavefunctions. Then, mu=rho_up-rho_dw where rho is the charge on the 
atomic wavefunctions of each atom.

PS having a spell-checker installed could be a good idea ;-)
