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

I used the Heisenberg model for S = 1/2 such as done on experiment, but I still having difficulty to make couling of lattice cubic, my lattice stucture is like in enclosure file

Dear all,,


When I simulate the susceptibility of Cd0.3Mn0.7Te, I had a problem of my results. The result has obtained not to synchronize with theory. I get 5K of Neel Temperature, while the theory is 23 of Neel Temperature. is there's any mistake with my cubic lattice?

my cubic lattice is :

Hi,

If the theory does not agree with experiment you might have used an inappropriate model. How did you obtain all your coupling constants?

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?
