Abstract

In this work, an interlayer perpendicular standing spin wave mode is observed in the skyrmion-hosting [Pt/Co/Ta]10 multilayer by time-resolved magneto-optical Kerr effect measurements. The observed interlayer mode depends on the interlayer spinpumping and spin transfer torque among the neighboring Co layers. This mode shows monotone increasing frequency-field dependence which is similar to the ferromagnetic resonance mode, but with higher frequency range. Besides, the damping of the interlayer mode is found to be a relatively low constant value of 0.027 which is independent of the external field. This work expound the potential application of the [heavy-metal/ferromagnetic-metal]n multilayers for skyrmion-based magnonic devices which can provide multiple magnon modes, relatively low damping, and skyrmion states, simultaneously.
