Ising Model Monte Carlo - interpretations

Click For Summary
SUMMARY

The discussion centers on the behavior of the classical Ising Model during Monte Carlo simulations, particularly the phenomenon of magnetization saturation at low temperatures. Users observe that starting from a ferromagnetic state, the magnetization remains stable across a range of temperatures, only to decline sharply as the system approaches the critical (Curie) temperature. This behavior indicates a strong correlation between temperature and magnetization, suggesting that the system exhibits resistance to thermal fluctuations until a critical threshold is reached.

Ising Model Monte Carlo -- interpretations

Hi,

I am trying to solve and understand the classical Ising Model through a classical Monte Carlo simulation. I notice that if I begin with a ferromagnetic initial state, then the magnetization is more or less constant for a wide range of temperatures before it suddenly begins to drop near the critical (Curie) temperature. Why is this saturation observed at low temperatures in the simulation? It is almost as if the system rejects an increase in temperature by maintaining the magnetization.

Thanks in advance!

Any ideas, anyone?
