Giant magnetoimpedance effect in Co2FeAl single layered and Co2FeAl/Ag multilayered films in amorphous substrates

We investigate the structural, quasi-static and dynamic magnetic properties of a Co2FeAl single layered film and a Co2FeAl/Ag multilayer, both grown onto amorphous substrate. We verify that both films have A2 structure and anisotropic magnetic behavior, as well as present the well-known magnetoimp...
