Efeito do tratamento térmico na relaxação magnética de microfios amorfos de CoFeSiB recobertos por vidro
(Universidade Federal de Santa Maria, 2012-02-27)
Magnetoimpedance has been proved to be an excellent tool to study the magnetization
dynamics and the ferromagnetic resonance (FMR) linewidth provides a convenient way
for measuring damping parameters in magnetic materials. ...
Detecção elétrica da ressonância ferromagnética em filmes finos de NiFe/FeMn
(Universidade Federal de Santa Maria, 2018-07-20)
Devices based on effects that generate a dc voltage in ferromagnetic ressonance (FMR)
condition are of great interest for broadband communication applications, since they allow
the rectification of radio frequency signals ...
Caracterização de multicamadas de NiFe/FeMn para medidas de magnetoimpedância assimétrica abaixo de 2 GHz
(Universidade Federal de Santa Maria, 2018-11-13)
In this work the giant magnetoimpedance effect (GMI) was investigated in exchange biased
Ni81Fe19/Fe50Mn50 bilayers. The study samples were deposited on glass substrate
by magnetron sputtering. The exchange bias (EB) was ...
