Abstract
Spin currents absorption effect into a Pt wire is demonstrated by mean of the nonlocal spin valve measurement. Using this absorption effect, an inverse spin Hall effect is successively observed at room temperature. Moreover, the direct spin Hall effect is also demonstrated by a Pt spin current generator with nonlocal detection technique. The spin Hall conductivity in the Pt wire is 260 Scm at room temperature, which is 104 times larger than that in semiconductor systems. Temperature dependence of the spin Hall conductivity is also investigated.
