We study ground-state and thermal pairwise concurrence in one-dimensional frustrated spin-1/2 antiferromagnetic J(1)-J(2) model embedded in a uniform magnetic field. Frustration is found to change the magnetic field dependence of concurrence qualitatively. Especially concurrence between second and third neighbors show interesting behavior around the critical values of the external magnetic field. (c) 2005 Elsevier B.V. All rights reserved.
