Abstract
Proper understanding of spin dynamics in the magnetic multilayer system is a necessary step for the fabrication of practical magnetic devices. In the present study, spin dynamics in the [Co/Ni]N/Ti multilayers at various Co and Ni layer thicknesses were obtained by optical method with the aim to identify the structural effects on the Gilbert damping constant of the multilayer system. It was found that the change of crystallinity and magnetocrystalline anisotropy depending on the relative thicknesses ratio of Co and Ni layers work as the main factor to determine the Gilbert damping behavior. © 2016 Elsevier B.V.
