“…The Ag 3d 5/2 and 3d 3/2 peaks occur at a BE of 367.8 and 373.8 eV, respectively, and correspond to metallic silver. [25] The result demonstrates that only one form of Ag is present in solution, in the form of Ag 0 . There is no evidence for additional components in the Ag 3d spectrum, which indicates the complete reduction of the Ag + ions in the UVirradiated TSA solution.…”

In this paper we describe the size-controlled synthesis of a silver nanocomplex based on the reduction of silver nitrate (AgNO 3 ) by UV-irradiated tungstosilicate acid [H 4 (SiW 12 O 40 ), TSA] solution. This method allows the synthesis of ellipsoidal particles with an average size that is tunable between 2.4 and 84 nm by varying the molar ratio of silver nitrate to TSA, the pH of the reaction solution, and the reaction temperature. Silver nanorods can be formed from the

“…As a result, two-magnon scattering is also lower in case of Co/Au. Furthermore, Au has a lower density of electrons in d band states at the Fermi level compared to Pt [38], which therefore contributes very weakly to the intrinsic damping. to Co/Pt.…”

The evolution of damping in Co/Pt, Co/Au, and Ni 81 Fe 19 /Pt bilayers was studied with increasing nonmagnetic (NM) heavy-metal layer thicknesses in the range 0.2 nm t NM 10 nm, where t NM is the NM layer thickness. Magnetization precession was measured in the time domain using time-resolved magneto-optical Kerr effect magnetometry. Fitting of the data with a damped sinusoidal function was undertaken in order to extract the phenomenological Gilbert damping coefficient α. For Pt-capped Co and Ni 81 Fe 19 layers a large and complex dependence of α on the Pt layer thickness was observed, while for Au capping no significant dependence was observed. It is suggested that this difference is related to the different localized spin-orbit interaction related to intermixing and to d-d hybridization of Pt and Au at the interface with Co or Ni 81 Fe 19 . Also it was shown that damping is affected by the crystal structure differences in FM thin films and at the interface, which can modify the spin-diffusion length and the effective spin-mixing conductance. In addition to the intrinsic damping an extrinsic contribution plays an important role in the enhancement of damping when the Pt capping layer is discontinuous. The dependence of damping on the nonmagnetic layer thickness is complex but shows qualitative agreement with recent theoretical predictions.
