Magnetoimpedância em multicamadas de Ni81Fe19/Cu com a corrente de sonda perpendicular ao plano do filme
(Universidade Federal de Santa Maria, 2006-06-02)
In this work the behavior of the magnetoimpedance (MI) in ferromagnetic
multilayered (Ni81Fe19/Cu) produced by magnetron sputtering was studied. In all
measurements, the probe current was applied perpendicularly to the ...
Deposição de nano-grãos de Co em uma matriz de CoO/Al2O3 por Magnetron Sputtering
(Universidade Federal de Santa Maria, 2007-10-20)
Granular magnetic systems can be composed by magnetic particles or clusters with size of some nanometers. These magnetic nanoparticles present different magnetic order phases, as superparamagnetic, and they can be embedded ...
Deposição de nano-camadas de VO2 por Magnetron Sputtering
(Universidade Federal de Santa Maria, 2007-04-13)
The vanadium dioxide (VO2) shows a metal-insulator transition (MIT) near the room temperature with huge changes in its electrical and optical behavior. Both the
electrical and optic properties, and even the transition ...
