Dear all,
I am using the Quantum ATK 2021-06 version and I have calculated the Heisenberg exchange coupling constants and plotted the magnon dispersion. I would like to know the procedure of mapping the model to DFT. Particularly, my question is: does ATK include the magnetic anisotropy energy in its calculations in plotting magnon dispersion? if yes, how? I mean using the anisotropy term in the Heisenberg spin model or is it affected by the DFT calculations on Jij parameters?
I would be very grateful if you could give me a hint.
Thank you.
