Why are there so many spikes in this spin spiral (q) vs Energy plot?

28 November 2022 0 3K Report

I have been trying to find out the ground state spin spiral configuration for an off-stoichiometric compound along different crystallographic directions and I have encountered these kinds of plots. Might there be a specific reason for this behavior? Because the stoichiometric structures give me a smooth curve for each crystallographic direction.
