Gilbert Damping in Ni/Co Multilayer Films Exhibiting Large Perpendicular Anisotropy

概要
- 論文の詳細を見る
Gilbert damping is reported in perpendicularly magnetized Ni/Co multilayer films with Pt buffer and capping layers, and investigated through the time-resolved magneto-optical Kerr effect under various applied magnetic field strengths and directions. Both damping constant $\alpha$ and perpendicular magnetic anisotropy energy $K_{\text{u}}$ depend strongly on layer thickness and bilayer periodicity, and rise to approximately 0.08 and 8 Merg/cm3, respectively. The Gilbert damping rate depends linearly on inverse multilayer thickness, indicating that large damping in the Ni/Co multilayers stems from its interfaces in contact with the Pt layers.
