Abstract
A new field has emerged called spintronics (spin-based electronics), where the spin of electrons rather than the charge carries information. This may offer opportunities for a new generation of electronic devices. Measuring spin currents in semiconductors plays a key role in spintronics. In this review article, starting from the basic properties of spin currents and the current experimental techniques for spin current measurements, we briefly introduce our theory on optical effects of spin currents in the direct-gap semiconductors, i.e., the Faraday rotation and nonlinear optics, which provide a direct measurement of pure spin currents in semiconductors.
