For an ordered crystal, we generally converge the k-mesh resolution for a primitive cell or other smaller supercells. We then use this resolution for any other size of the supercell for the same material. Can we do the same with special quasi-random structures, given that they are disordered?
I've noticed that on doing spin-polarised relaxation for various SQS of different sizes of a magnetic material, they each might turn out to have different magnetic moments. That is inconsistent, though I don't know if this is the case with any magnetic material.
I thought since SQS are disordered, the local atomic arrangement/ environment shall be different for different SQS, both, of the same and different sizes. This might lead to different magnetic moments. What is your understanding of the topic?
Also, can we establish a standard method on the convergence of k-mesh resolution for SQS?
