      abstract     = {Modern spintronics relies on the generation of spin
                      currents through spin-orbit coupling. The spin-current
                      generation has been believed to be triggered by
                      current-induced orbital dynamics, which governs the angular
                      momentum transfer from the lattice to the electrons in
                      solids. The fundamental role of the orbital response in the
                      angular momentum dynamics suggests the importance of the
                      orbital counterpart of spin currents: orbital currents.
                      However, evidence for its existence has been elusive. Here,
                      we demonstrate the generation of giant orbital currents and
                      uncover fundamental features of the orbital response. We
                      experimentally and theoretically show that orbital currents
                      propagate over longer distances than spin currents by more
                      than an order of magnitude in a ferromagnet and nonmagnets.
                      Furthermore, we find that the orbital current enables
                      electric manipulation of magnetization with efficiencies
                      significantly higher than the spin counterpart. These
                      findings open the door to orbitronics that exploits orbital
                      transport and spin-orbital coupled dynamics in solid-state
                      devices.},
