Comparative study on magnetoresistance of carbon-cobalt nanocomposite thin films grown by pulsed laser deposition
S. Sergeenkov, C. Cordova, L. Cichetto +4
We present a comparative study on the influence of applied magnetic field on the resistance of thin films (with , and ) grown on substrate by…
Magnetic phases evolution in the LaMn1-xFexO3+y system
O. F. de Lima, J. A. H. Coaquira, R. L. de Almeida +2
We have investigated the crystal structure and magnetic properties for polycrystalline samples of LaMn1-xFexO3+y, in the whole range x=0.0 to x=1.0, prepared by solid state reactio…
Magnetic and superconducting properties of RuSr2 Gd1.5Ce0.5Cu2O10-x samples: dependence on the oxygen content and ageing effects
C. A. Cardoso, A. J. C. Lanfredi, A. J. Chiquito +5
The magnetic and superconducting properties of RuSr2Gd1.5Ce0.5Cu2O10-x polycrystalline samples with different oxygen doping level are presented. A strong suppression of the superco…
