| 中文摘要 | We propose that stable two-dimensional (2D) ferromagnets can be made of regular single-layered lattices of single-molecule nanomagnets with enough perpendicular uniaxial magnetic anisotropy on appropriate substrates by controlling the internanomagnet magnetic interaction. Our Monte Carlo simulated results show that such ideal 2D ferromagnets are thermodynamically stable when the anisotropy is strong enough. Magnetization, fourth-order Binder's cumulant, specific heat, and magnetic susceptibility as functions of temperature are calculated for various anisotropy parameters. If the anisotropy energy equals 80 K, approximately that of the Mn-12, the T-C varies from 0 to 15 K depending on different internanomagnet coupling constants. Such stable spin systems, experimentally accessible, should be promising for information applications. |
