|Title:||Tuning of the magnetization dynamics in as-sputtered FeCoSiN thin films by various sputtering gas pressures||Authors:||Xu, F.
|Issue Date:||2008||Citation:||Xu, F., Phuoc, N.N., Zhang, X., Ma, Y., Chen, X., Ong, C.K. (2008). Tuning of the magnetization dynamics in as-sputtered FeCoSiN thin films by various sputtering gas pressures. Journal of Applied Physics 104 (9) : -. ScholarBank@NUS Repository. https://doi.org/10.1063/1.3006006||Abstract:||In this work, we investigate the influence of various sputtering gas pressures on the high-frequency magnetization dynamics in as-sputtered FeCoSiN granular thin films. The permeability spectra are measured with the shorted microstrip transmission-line perturbation method and analyzed with the Landau-Lifshitz-Gilbert equation. The dependence of the effective damping coefficient on the external fields is fitted with a power law. The measurement and fitting results show that both the effective and the intrinsic damping coefficients in the magnetization dynamics can be conveniently and effectively tuned by changing the sputtering gas pressure. The physical origin of the influences is suggested to be related to the stress in the films. © 2008 American Institute of Physics.||Source Title:||Journal of Applied Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/98465||ISSN:||00218979||DOI:||10.1063/1.3006006|
