Phase diagrams of a cylindrical spin-1 ising nanowire within the presence of the crystal field and the transverse field
arXiv:1312.7728
Abstract
Within the framework of the effective-field theory (EFT) with correlations, the phase diagrams of a cylindrical spin-1 Ising nanowire is investigated, depending on the ratio of the Hamiltonian parameters. We discuss in detail the influence of interfacial coupling, crystal field and transfer field ratio on the phase diagrams, and some characteristic phenomena have been found such as tricritical point and first-order transitions.
