  text: Controlling the intensity of emitted light and charge current is the basis
    of transferring and processing information1. By contrast, robust information storage
    and magnetic random-access memories are implemented using the spin of the carrier
    and the associated magnetization in ferromagnets2. The missing link between the
    respective disciplines of photonics, electronics and spintronics is to modulate
    the circular polarization of the emitted light, rather than its intensity, by
    electrically controlled magnetization. Here we demonstrate that this missing link
    is established at room temperature and zero applied magnetic field in light-emitting
    diodes2,3,4,5,6,7, through the transfer of angular momentum between photons, electrons
    and ferromagnets. With spin–orbit torque8,9,10,11, a charge current generates
    also a spin current to electrically switch the magnetization. This switching determines
    the spin orientation of injected carriers into semiconductors, in which the transfer
    of angular momentum from the electron spin to photon controls the circular polarization
    of the emitted light2. The spin–photon conversion with the nonvolatile control
    of magnetization opens paths to seamlessly integrate information transfer, processing
    and storage. Our results provide substantial advances towards electrically controlled
    ultrafast modulation of circular polarization and spin injection with magnetization
    dynamics for the next-generation information and communication technology12, including
    space–light data transfer. The same operating principle in scaled-down structures
    or using two-dimensional materials will enable transformative opportunities for
    quantum information processing with spin-controlled single-photon sources, as
    well as for implementing spin-dependent time-resolved spectroscopies.
