| Abstract: | The size effects on different properties, such as magnetization M, Curie temperature TC and band gap Eg of ferromagnetic semiconducting EuS nanoparticles are studied based on the d-f model and using a Green's function technique. We have shown that M and TC are decreased compared with the bulk material, whereas Eg is increased. The results are in qualitative agreement with the experimental data. |
