Abstract
The dynamical properties of an infinite–ranged SG at finite temperature are investigated. We have performed computer simulations on four cases. Within the replica treatment thermodynamic properties are independent of inthe SG phase. The ground-state energies shows that some properties may be modified sufficiently close to the ferromagnetic phase boundary. We found that in the presence of an external magnetic field the ground state energy is decreasing by increasing and becomes linear with . The internal energy obtained is compared with the predicted value from Monte Carlo simulation. Finally, in the presence of , the magnetization and the square mean of the local magnetization are found to be non zero. This means that there’s no phase transition and the system becomes FM.
