Özet

A two-leg ladder spin-1 model is constructed and examined in terms of the exact recursion relations. The model consists of two interchain and one intrachain bilinear exchange interaction parameters J in addition to the single ion anisotropy parameter D and external magnetic field H. Both the ferromagnetic, J > 0, favoring the parallel alignment between the nearest-neighbor spins and antiferromagnetic, J < 0, for antiparallel alignment of the nearest-neighbor spins are considered. The thermal and external magnetic field variations of magnetizations and susceptibilities belonging to each chain are examined. Different regions with ferromagnetic, ferrimagnetic, antiferromagnetic, non-magnetic, or chaotic phases are observed. Magnetization plateaus and more than one susceptibility peak are also found.
