| Resumo | |
This work reports the effect of Mn, Fe, Co, and Cu low doping (similar to 3 at. %) on the ferromagnetic behavior of oxygen-defective CeO2-delta films electrodeposited on SiO2/Si(001). Our results indicate that the incorporation of a small number of 3d dopants with unoccupied outermost atomic orbitals, presumably magnetically active, strongly perturb the ferromagnetic ground-state associated with the network of electron clouds surrounding oxygen vacancies. As a consequence, a strong loss of magnetization occurs and saturation magnetization becomes uncorrelated with number of oxygen vacancies.
