      abstract     = {Terahertz spintronics offers the prospect of devices which
                      are both faster and more energy-efficient. A promising route
                      to achieve this goal is to exploit current-induced
                      spin-orbit torques. However, the high-frequency properties
                      of these quantities remain unexplored both experimentally
                      and theoretically, within a realistic material-specific
                      approach. Here we investigate the dynamical transverse
                      components of the torques and uncover contributions
                      longitudinal to the magnetic moment capable of changing its
                      magnitude. We show that, while the torques can be
                      drastically altered in the dynamical regime, the effective
                      magnetic fields that accompany them present a
                      frequency-independent behaviour, ranging from the static
                      limit up to the terahertz domain — including the
                      ferromagnetic resonance of the system. The outcomes of this
                      work point to new ways to control magnetic units in
                      next-generation spintronic devices.},
