Abstract
The purpose of this paper is to study the magnetic properties of a fullerenelike structure geometry X 20 X 60 and X 70 where the symbol X can be assigned to any magnetic atom Such structures are formed by atoms with spin σ = 1/2 Using the Monte Carlo computation the thermal behavior of the magnetizations and susceptibilities of such systems in the ferromagnetic case are studied We find that the critical temperature increases nonlinearly when increasing the number of atoms in the studied system Otherwise the coercive field increases linearly when the number of atoms in the structure increases
