Magnetic Properties of Gd-Doped Fe3O4 Nanoparticles
Source abstract
Abstract
The magnetic properties of pure and rare earth ion-doped Fe3O4 nanoparticles are investigated using a microscopic model and the Green’s function theory. The magnetization Ms and Curie temperature TC are calculated depending on size, temperature and Gd doping concentration. Ms and TC decrease with decreasing nanoparticle size and with increasing the doping concentration. The band gap energy increases with decreasing size and Gd dopants. The obtained results are in good agreement with the experimental data.
