Study of CoFe2O4/CoFe2 nanostructured powder
E. S. Ferreira, E. F. Chagas, A. P. Albuquerque +2
We report an experimental study of the CoFe2O4/CoFe2 nanocomposite, a nanostructured material formed by hard (CoFe2O4) and soft (CoFe2) magnetic materials. The precursor material,…
Study of soft/hard bimagnetic CoFe2/CoFe2O4 nanocomposite
E. H. Coldebella, E. F. Chagas, A. P. Albuquerque +3
We report an experimental study of the bimagnetic nanocomposites CoFe2/CoFe2O4.The precursor material, CoFe2O4 was prepared using the conventional stoichiometric combustion method.…
Exchange-spring behavior in bimagnetic CoFe2O4/CoFe2 nanocomposite
Gustavo C. P. Leite, Edson F. Chagas, Rodrigo Pereira +4
In this work we report a study of the magnetic behavior of ferrimagnetic oxide CoFe2O4 and ferrimagnetic oxide/ferromagnetic metal CoFe2O4/CoFe2 nanocomposites. The latter compound…
Cationic exchange in nanosized ZnFe2O4 spinel revealed by experimental and simulated near-edge absorption structure
S. J. Stewart, S. J. A. Figueroa, J. M. Ramallo-López +4
The non-equilibrium cation site occupancy in nanosized zinc ferrites (6-13 nm) with different degree of inversion (0.2 to 0.4) was investigated using Fe and Zn K-edge x-ray absorpt…
