      abstract     = {We propose a mechanism of torque generation by injection of
                      an orbital current, which we call orbital torque. In a
                      magnetic bilayer consisting of a nonmagnet (NM) and a
                      ferromagnet (FM), we consider a situation where the
                      spin-orbit coupling (SOC) is present only in the FM.
                      Although the SOC is absent in the NM, the orbital Hall
                      effect can arise in the NM. When the resulting orbital Hall
                      current is injected to the FM, the SOC of the FM converts
                      the orbital angular momentum into spin, which exerts torque
                      to the magnetization of the FM. Remarkably, even for small
                      SOC strength comparable to that of 3d FMs, the orbital
                      torque can be comparable to the spin torque induced by the
                      spin Hall effect of the NM with strong SOC. This provides a
                      way to experimentally probe the OHE and opens a venue to
                      achieving spin-torque devices based on light elements that
                      exhibit gigantic orbital response. Experimental implications
                      are discussed.},
