  We study the effects of electrostatic gating on the current-induced phenomena
in ultrathin ferromagnet/heavy metal heterostructures. We utilize heterodyne
detection and analysis of symmetry with respect to the direction of the
magnetic field to separate electric field contributions to the magnetic
anisotropy, current-induced field-like torque, and damping torque. Analysis of
the electric field effects allows us to estimate the Rashba and the spin Hall
contributions to the current-induced phenomena. Electrostatic gating can
provide insight into the spin-orbit phenomena, and enable new functionalities
in spintronic devices.
