Spin current is a key concept of spintronics. So far, several methods has been known to generate spin current, including the spin pumping effect induced by magnetization dynamics. For detection of spin current, the inverse spin Hall effect has been widely used. In this talk, we will study these effects based on a microscopic theory, and discuss the spin-charge conversion mechanism. We will show that there is a novel monopole in the spin pumping + inverse spin Hall systems. The monopole, a spin damping monopole, induces the electric current via the Ampere's law and plays an essential role in converting spin transport to charge transport.
