Investigation of the Magnetic Features of the Fullerene-Dimer-Like Nanostructure (C ₆₀)₂: A Monte Carlo Study

The current investigation employs Monte Carlo simulations to explore the magnetic features of a Fullerene-dimer-like nanostructure ( C 60 ) 2 characterized by the spin σ− 1. It explores how the coupling interaction J σ , the biquadratic parameter K , the external magnetic H and the crystal D fields influence the thermal and magnetic features of the nanostructure, particularly the blocking temperature ( T B ). The results also highlight the dependence of hysteresis cycles and the coercive magnetic field Hc on the values of J σ , K , and D , with significant variations at lower temperatures. The findings indicate the distinctive magnetic behavior of the Fullerene-dimer-like nanostructure ( C 60 ) 2 potentially useful in various technological applications.
