my lattice is fcc but I can't find how many lattice in a unit cell,, I make 10 spin in simulation just for exercise.
The
goal of this simulation is getting the curve of magnetization and the
curve of suseptibility to calibrate with the experimen...
if my xml was wrong, please give me some sugestion to correct it!
How to make the coupling in my lattice not constant?

Are you sure that you only want to simulate 10 spins? How do you define a phase transition for 10 spins? Don't you want to simulate a lattice? In a lattice you should give the unit cell. Do you have a simple cubic, fcc or bcc lattice? How many spins per unit cell?
