For cubic system do we need to maintain uniform cell length in all three direction while making a supercell?

Suppose we have a cubic unit cell. We need doping of the alloy with 5 at.%. For that we need to make a supercell for representation the doped composition. So to maintain cubic symmetry should we...

How to calculate the inter-site exchange coupling parameters Jij between atoms? Do we have to assign spin values only for the atoms of Jij?

The inter-site exchange coupling parameters Jij are calculated as a function of the inter-site distance in alloys. We know we can find J by total energy difference between FM and AFM , then that...
