Adsorption and doping were found to affect the magnetic properties of bilayer graphene, with the antiferromagnetic exchange coupling significantly influencing quantum fluctuations in the system.
Adsorption and doping affect the magnetic properties of bilayer graphene. The triangular structure six-sublattice system is investigated in this study. The Hamiltonian of the system is given under the framework of the Heisenberg model, and the spin spectrum and magnetization in the ground state of the system are solved using linear spin-wave theory and the delayed Green?s function. On this basis, the quantum fluctuations are defined, and the effects of the exchange coupling, magnetocrystalline anisotropy, and spin quantum number on the quantum fluctuations are discussed. The results indicate that the antiferromagnetic exchange coupling of the system significantly affects the quantum fluctuations.
