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.…
Antiferromagnetic spin chain behavior and a transition to 3D magnetic order in Cu(D,L-alanine)2: Roles of H-bonds
Rafael Calvo, Rosana P. Sartoris, Hernan L. Calvo +2
We study the spin chain behavior, a transition to 3D magnetic order and the magnitudes of the exchange interactions for the metal-amino acid complex Cu(D,L-alanine)2.H2O, a model c…
Thermal effect on magnetic parameters of high-coercivity cobalt ferrite
E. F. Chagas, A. S. Ponce, R. J. Prado +3
We prepared very high-coercivity cobalt ferrite nanoparticles using short-time high-energy mechanical milling. After the milling process, the coercivity of the nanoparticles reache…
High coercivity induced by mechanical milling in cobalt ferrite powders
A. S. Ponce, E. F. Chagas, R. J. Prado +3
In this work we report a study of the magnetic behavior of ferrimagnetic oxide CoFe2O4 treated by mechanical milling with different grinding balls. The cobalt ferrite nanoparticles…
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…
