Ground State Phase Diagrams of Borophene-Like Nanostructures with RKKY Interactions: A Monte Carlo Study

Abstract

This study investigates the ground state phase diagrams of a borophene-like nanostructure containing atoms with spin values S-1 and σ-3/2. In addition, the magnetic features of the nanosystem, comprising bilayers separated by non-magnetic planes L = 1, 2, and 3, were examined under varying physical parameters employing the Blum-Capel model under the Metropolis algorithm with the RKKY interactions. The Monte Carlo analysis indicates that the rising number of non-magnetic layers impacts the magnetization M and magnetic susceptibility χ marking the system’s transition from the ferromagnetic to superparamagnetic state and also affects the blocking temperature t_B for L ≤ 3. Also, the hysteresis cycles exhibit magnetization plateaus as the parameter L rises, offering valuable insights in use of the borophene nanostructure for advancing spintronics and data storage nanotechnologies.
