Abstract :
The size effect on the magnetic and electronic properties of an impurity in finite systems is investigated based on the Anderson admixture model in real space. Within the self-consistent mean field approximation, it is found that the formation of the local magnetic moment strongly depends on the size of finite linear quantum chains up to a few nanometers. The density of states for the local electrons is also obtained
