Abstract
We present the exact solution of a family of two-spins models. The models are solved by the algebraic Bethe ansatz method using the -invariant -matrix and a multi-spins Lax operator. The interactions are by the Heisenberg spins exchange. We are also considering magnetic -fields and a term for Haldane single spin anisotropy.
