Abstract

The inverse spin Hall effect used for detection of spin currents was observed by voltage measurements in bilayers of normal metal (NM)/ferromagnetic metal (FM), using Nb, Mo and Bi as normal metal and Permalloy (Py, Ni₈₁Fe₁₉) as ferromagnetic metal. The spin current was generated by the spin pumping effect with ferromagnetic resonance. The samples were deposited by dc magnetron sputtering at room temperature on Si (001) substrates. The three bilayers of Nb/Py, Mo/Py and Bi/Py had a spin-orbit coupling large enough to observe the voltage generation by spin Hall effect
