A set of localized spins coupled through exchange interaction was studied, subjected to an external magnetic field. It was demonstrated that entanglement could be controlled and tuned by varying the anisotropy parameter in the Hamiltonian for such a class of one dimensional magnetic systems and by introducing impurities into the systems. It was found that for certain parameters, the entanglement was zero up to a critical point λ c, where a quantum phase transition occurred, and was different from zero above λc.
