Magnon dispersion
« on: January 25, 2024, 12:13 »
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.

Hi,

No, the magnetic anisotropy energy is not included in the magnon bandstructure.

Kind regards
