The intrinsic Gilbert damping constant in magnetic multilayers could be a signature of the spin current generation in the spin-pumping effect. In such research, materials with strong spin-orbit coupling, such as 5d heavy metals, are usually employed. Recently, the orbital-pumping effect, which works as a source of orbital current generation, has been reported in materials with 3d transition metals with weak spin-orbit coupling. We have also reported that the intrinsic Gilbert damping in the V/Fe/MgO multilayer is influenced by MgO overlayer thickness, which may be related to the orbital magnetic moment in the system. In this study, we report the intrinsic Gilbert damping of the V/Fe/MgO system with changing the magnetization direction.
