| Resumo: | Dynamic magnetic behavior, through magnetoimpedance effect, is investigated in non-magnetostrictive
multilayered films of Ni81Fe19/(Ag,Ta) grown on glass and flexible substrates. The magnetoimpedance
measurements are performed in a wide range of frequencies (from 0.01 GHz up to 3.0 GHz) and are interpreted in terms of the structural and quasi-static magnetic properties of the films. In particular, Ni81Fe19/Ag multilayered films grown on glass and flexible substrates present very similar results, with
MImax values of 40% at around 0.5 GHz. For the Ni81Fe19/Ta multilayered film on glass substrate, higher MImax value is observed, 60% at around 0.45 GHz, whereas for the one produced on flexible substrate, 28% at around 0.3 GHz. Thus, the fact that the produced multilayered films present good MI performance,
irrespective of the employed substrate, opens new possibilities for technological applications, making
easier the integration of these samples as a sensor element in MI based electronic devices, where flexible
substrates can be used with the same efficiency |
