Monte Carlo study of magnetic structures in rare-earth amorphous alloys

Using the Monte Carlo method, we studied magnetic properties of the models of Re-Tb and Re-Gd amorphous alloys as well as pure amorphous Tb and Gd. The magnetic phase diagrams for the models of amorphous Tb and Gd were constructed. We determined the values of D/J0 (for Tb) and J1/|J2| (for Gd) at wh...
