“…To best of our knowledge, theoretically, a large number of researches on single-layer graphene-like nanostructures based on MC method have been carried out [17,21,[25][26][27]. The physical properties of the edge-decorated nanostructures are more focused on graphene-like nanoribbons by the transfer matrix method [58] and DFT [59] as well as monolayer graphene-like nanoparticles by MC method [60]. However, the research on the magnetic properties of multilayer edge-decorated nanoparticles based on MC method is still insufficient, especially less attention has paid to the ground-state properties and magnetocaloric effects of the multilayer edge-decorated nanoparticles.…”

In this paper, the thermodynamic characteristics, magnetocaloric effect and ground-state properties of an edge-decorated Ising multilayer nanoparticle with graphene-like structure are studied by Monte Carlo simulation. The results reveal that size effect, crystal field, exchange coupling, and applied magnetic field can control the magnetic behaviors of the system. In addition, the curves of magnetic entropy change and relative cooling power (RCP) are given induced by various physical parameters.

“…The low-temperature magnetization data of another 3d-4f heterobimetallic coordination polymer [Dy (hfac) 2 (CH 3 OH) 2 Cu(dmg)(Hdmg) 2 ] n (H 2 dmg = dimethylglyoxime; Hhfac = 1,1,1,5,5,5-hexafluoropentane-2,4-dione) have been successfully interpreted within the spin-1/2 Ising-Heisenberg orthogonaldimer chain [16,17]. It is worthwhile to remark that several other exactly solved Ising-Heisenberg spin chains have provided unbiased descriptions of various intriguing quantum phenomena including quantized magnetization plateaus [18,19], enhanced magnetocaloric effect [19,20], partition function zeros [21], quantum teleportation [22], unconventional "fire-and-ice" ground states [23], pseudo-transitions [24], quantum coherence [25], quantum nonlocality [26], quantum Fisher information [27] as well as nanostructures [28,29].…”

The spin-1/2 Ising-Heisenberg branched chain, inspired by the magnetic structure of three isostructural polymeric coordination compounds [(Tp)2Fe2(CN)6X (bdmap)Cu2(H2O)] ⋅ H2O to be further denoted as Fe2Cu2 (Tp = tris(pyrazolyl)hydroborate, bdmapH = 1,3-bis(dimethylamino)-2-propanol, HX = acetic acid, propionic acid or trifluoroacetic acid), is rigorously studied using the transfer-matrix method. The overall ground-state phase diagram reveals three distinct phases: a quantum antiferromagnetic phase, a quantum ferrimagnetic phase and a classical ferromagnetic phase. In the zero-temperature magnetization curve, two quantum ground states are manifested as intermediate plateaus at zero and half of the saturation magnetization, while the magnetization reaches its saturated value within the classical ferromagnetic phase. The bipartite entanglement between nearest-neighbor Heisenberg spins is more pronounced in the quantum ferrimagnetic phase compared to the quantum antiferromagnetic phase due to a fully polarized nature of the Ising spins. A reasonable agreement between theoretical predictions for the spin-1/2 Ising-Heisenberg branched chain and experimental data measured for a temperature dependence of the magnetic susceptibility and a low-temperature magnetization curve suggests strong antiferromagnetic coupling between nearest-neighbor Cu2+-Cu2+ magnetic ions and moderately strong ferromagnetic coupling between nearest-neighbor Cu2+-Fe3+ magnetic ions in the polymeric compounds Fe2Cu2. A thermal entanglement between nearest-neighbor Cu2+-Cu2+ magnetic ions persists up to a relatively high threshold temperature T ≈ 224 K and undergoes a transient magnetic-field-driven strengthening.
