Abstract
A power series expression of the exact solution of the one-dimensional (1D) Hubbard model in an external magnetic field is derived to study the antiferromagnet-ferromagnet transition in the critical region. Asi de from the magnetization curve, the critical field and susceptibility are analytically evaluated, and the results of these quantities in so me limiting cases are discussed.
