Ferrimagnetism and spin canting of ZnFe2O4 nanoparticles embedded in ZnO matrix
G. F. Goya, E. R. Leite
The structural and magnetic properties of ZnFe2O4 nanoparticles embedded in a non-magnetic ZnO matrix are presented. X-ray diffractograms and Transmission Electron Microscopy (TEM)…
Magnetic dynamics of single domain Ni nanoparticles
G. F. Goya, F. C. Fonseca, R. F. Jardim +4
The dynamic magnetic properties of Ni nanoparticles diluted in an amorphous SiO2 matrix prepared from a modified sol-gel method have been studied by the frequency f dependence of t…
Stable room temperature magnetic graphite
H. Pardo, F. M. Araujo-Moreira, R. Faccio +6
Carbon materials are attracting increasing attention due to the novelty of the associated physical properties and the potential applications in high-tech devices. The possibility t…
Physical properties of single-crystalline fibers of the colossal-magnetoresistance manganite La0.7Ca0.3MnO3
C. A. Cardoso, F. M. Araujo-Moreira, M. R. B. Andreeta +5
We have grown high-quality single crystals of the colossal-magnetoresistance (CMR) material La0.7Ca0.3MnO3 by using the laser heated pedestal growth (LHPG) method. Samples were gro…
Superconductivity in sintered-polycristalline PrBaCuO
F. M. Araujo-Moreira, P. N. Lisboa Filho, S. M. Zanetti +2
Superconductivity in thin films and powders, and in single crystals of Pr-123 has been found by Blackstead et al. and Zou et al., respectively. Nevertheless, up to now it has never…
