| Popis: | An effective field method has been employed to study the magnetic properties of a ferrimagnetic mixed-spin Ising trilayer nanographene structure. The system is formed by alternate layers of two different spins atoms A (spin-1) and B (spin-½) arranged in a particular fashion A–B–A for which the nearest-neighbor spins of each layer are coupled ferromagnetically (JA and JB), whereas the cross atom interaction A-B (interlayer) is antiferromagnetic (JAB). We examined the effects of interlayer (or intra-layer) exchange coupling and single-ion anisotropy on the magnetization curves of the system. We found that the antiferromagnetic inter-layers (JAB |
