“…Furthermore, the magnetic behavior of graphene was successfully studied using effective field theory with correlations [33,34]. Other studies used the mean-field approximation to determine the magnetic properties and hysteresis behavior of a graphene layer with spin-3/2 [35] and with mixed spins (3/2; 3) [36]. Finally, the Monte Carlo simulation was used in numerous papers to study the thermodynamic and magnetic properties of graphene [37][38][39][40][41][42][43].…”

Using the mean-field approximation based on the Gibbs-Bogoliubov inequality for the free energy, we conducted an investigation into the magnetic properties and hysteresis behavior of a graphene Ising bilayer, where the top and bottom layers are occupied by spins σ = 3/2 and S = 5/2, respectively. The effects of exchange interactions, crystal fields, external magnetic field and temperature on thetotal magnetization, partial magnetizations of each layer, total magnetic susceptibility, blocking temperature and hysteresis loops of the system were thoroughly analyzed. The variations of the blocking temperature as a function of various parameters in the system's Hamiltonian were presented. Furthermore, we demonstrated the existence of multiple hysteresis loop behaviors under specificphysical conditions.

“…The combination of graphene with these tilted Dirac cone materials promises the development of new structures, known as heterostructures, which could offer an even wider range of theoretical and practical applications [28][29][30]. By combining the advantages of graphene in terms of conductivity and transparency with the unique characteristics of tilted Dirac cone materials, these heterostructures could revolutionize the fields of electronics and functional materials, thus paving the way for new opportunities in innovation [31][32][33][34][35].…”

This paper aims to theoretically analyze the behavior of Dirac fermions in tilted Dirac cone material, particularly those that have diffused a barrier potential. Our results show that the degree of tilt in the y-direction can lead to different collimations of the Dirac fermion beams relative to the Fermi and confinement surfaces. To study the transmission probability, we exploited our results numerically, taking into account the various configurations of the system and the different external and internal physical parameters by characterizing the behavior of fermionic transport in a proposed heterostructure. Our findings lay the groundwork for developing controllable electronicdevices utilizing Dirac fermion collimation, governed by the tilt parameter, enabling precise manipulation and enhanced functionality.
