I have recently been working with non-collinear antiferromagnetic systems. I understand that, in order to obtain spin density, one must obtain the electron density in one configuration of spin and subtract the electron density in the other configuration.
I am unsure as to how to go about this in my non-collinear system. Is it as simple as obtaining the electron density with my original antiferromagnetic configuration and then inverting the spin and running another SCF calculation? Is it necessary to restrict the spin configuration in any way?
If anyone has experience with this, please let me know!
