Languages of publication
Inverse spin Hall effect consists in conversion of spin currents into electric currents and has recently been observed using spin-pumping operated by ferromagnetic resonance in permalloy/Pt(Cr) thin film structures. We prepared several Co_2Cr_{0.4}Fe_{0.6}Al/Pt thin film structures to observe for the first time inverse spin Hall effect in bilayer structures comprising ferromagnetic half-metallic Heusler alloy. In but a few Co_2Cr_{0.4}Fe_{0.6}Al/Pt samples we succeeded in observing inverse spin Hall effect voltage of few microvolts by spin pumping resulting from ferromagnetic resonance. This confirms that spin polarized current can be transferred into Pt layer. Inverse spin Hall effect was 2-3 times larger than that detected in permalloy/Pt bilayer under the same conditions.
