Abstract

We investigate magnetic and thermal behaviours of one-dimensional antiferromagnetic spin-1 Ising chain with single-ion anisotropy at very low temperatures using the classical transfer matrix technique. Magnetic plateaus, phase diagram, specific heat, susceptibility of the spin chain have been evaluated numerically from the free energy. The results are in good agreement with the experimental data for the spin-1 compounds [Ni-2 (MedPt)(2) (mu-ox)(H-2 O)(2)](ClO4)(2)2H(2)O, [Ni-2 (MedPt)(2) (mu-ox)(mu-N-3)](ClO4)0.5H(2)O, Ni(C2H8N2)Ni(CN)(4) and Ni(C10H8N2)(2) Ni(CN)(4).H2O.
