Resumen:
The inverse spin Hall effect, present in
some metals, produces a charge accumulation at the end of a metallic when a
spin current passes through it [1,2]. Particularly, when a ferromagnetic
resonance experiment is performed on a ferromagnetic/non-magnetic bilayer (FM/NM),
a pure spin current is injected on the NM layer when the FM layer fulfills the resonance
condition. In this case, if the NM metal presents the inverse spin Hall effect,
it is possible to detect this spin injection by measuring a voltage at the end of the sample
[3]. We present in this work some recent results obtained in this kind of
systems and, based on the experimental results, we discuse the origin and properties
of this effect.
