Spin Magnetization Density

[juan...@gmail.com]

Dear Dirac developers,

Im working on induced current densities for some systems and I saw that it is possible to calculate in DIRAC the "spin magnetization density".

Here I have some doubts. If I'm not wrong, the spin magnetization density has the form:



(took it from Reiher's book) it can be calculated with the perturbed/unperturbed function. 


But then I saw this comment on "visual_in_point_F90":


so I'm not sure if I'm confussing something and/or that comment is not right.

There is another keyword also (".ROTS") under "**VISUAL" that I think it's to plot the contribution to the total current density via a spin-current -density like term:



 But again the mentioned comment makes me doubt.

Can you please clarify this for me? Sorry if this are basic questions.

Thanks,
Juan José

Dear Dirac Developers,

I'm sorry. The comment I referred to was not on last message.
I'm sending it know.
