Simulation of magnetic phase transitions in amorphous alloys of the Re-Gd system
Using the Monte Carlo method within the Heisenberg model, we studied the magnetic properties of amorphous alloys of the Re-Gd system and of pure amorphous gadolinium. The temperature dependences of spontaneous magnetization, magnetic susceptibility, and the Edwards-Anderson order parameter were determined. The possibility of the system transitioning to the spin-glass state was examined.
