Spin-current injection into an organic semiconductor $$kappa$$-(BEDT-TTF)$$_{2}$$Cu[N(CN)$$_{2}$$]Br film induced by the spin pumping from an yttrium iron garnet (YIG) film. When magnetization dynamics in the YIG film is excited by ferromagnetic or spin-wave resonance, a voltage signal was found to appear in the $$kappa$$-(BEDT-TTF)$$_{2}$$Cu[N(CN)$$_{2}$$]Br film. Magnetic-field-angle dependence measurements indicate that the voltage signal is governed by the inverse spin Hall effect in $$kappa$$-(BEDT-TTF)$$_{2}$$Cu[N(CN)$$_{2}$$]Br. We found that the voltage signal in the $$kappa$$-(BEDT-TTF)$$_{2}$$Cu[N(CN)$$_{2}$$]Br/YIG system is critically suppressed around 80 K, around which magnetic and/or glass transitions occur, implying that the efficiency of the spin-current injection is suppressed by fluctuations which critically enhanced near the transitions.
