摘要

This study explores the magnetic properties of a two-dimensional triangulene-like nanostructure using Monte Carlo simulations within a mixed-spin Blume-Capel model. We systematically analyze how the crystal field (D), external magnetic field (H), and anisotropic exchange couplings (Jxx and Jxy) affect the system’s magnetic behavior. Ground-state phase diagrams identify stable spin configurations at zero temperature, while temperature-dependent studies reveal changes in magnetization, susceptibility, and hysteresis. Our findings offer valuable insights into controlling the magnetic response of triangulene-like nanostructures, which are promising for applications in spintronics, nanoscale magnetic storage, and low-dimensional magnetism.
