Magnetoimpedância como ferramenta para a caracterização magnética de microfios amorfos
(Universidade Federal de Santa Maria, 2006-09-22)
The possibility of exploring the magnetic properties of amorphous microwires in technological applications has attracted the attention of the scientific community in the last years. Beyond, the magnetoimpedance effect has ...
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 ...
Processos de magnetização e magnetoimpedância em filmes com exchange bias
(Universidade Federal de Santa Maria, 2006-10-20)
In this work, the magnetization process and the magnetoimpedance effect in thin films with exchange bias were studied. We have investigated NiO/NiFe and NiFe/FeMn/Ta multilayer produced by magnetron sputtering on glass and ...
