摘要
We focus on the magnetic properties of the S = 1 Heisenberg chain with alternating antiferromagnetic and ferromagnetic exchange interactions J(1) and J(2). The magnetic behavior of this system is calculated as a function of the alternation parameter alpha = J(2)/\J(1)\, from a general numerical procedure based on closed spin chains of increasing length. These theoretical results are fitted to rational unified expressions, which are subsequently used to describe the magnetic behavior of a nickel (II) complex, [Ni(bipy)(N-3)(2)](n), exhibiting an alternating chain structure with a dominant ferromagnetic exchange.
