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 :

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?
