Hedgehog orbital texture in p-type tellurium and the antisymmetric nonreciprocal Hall response
Gabriele Maruggi, Jaime Ferreira, Elisa Baggio-Saitovitch +2
Tellurium is a gyrotropic, p-type Weyl semiconductor with remarkable electronic, optical, and transport properties. It has been argued that some of these properties might stem from…
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,…
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…
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…
