To enhance the damping of microwave magnetization dynamics, we investigate the effect of Nd-doping (0–3.0 at. %) into CoZr thin films. The saturation magnetization decreases with Nd-doping. The coercivities generally decrease in the case of 1.5 at. % Nd-doping, while increase in the case of 3.0 at. % Nd-doping. The magnetization dynamics is characterized with the permeability spectra, which are determined by the ferromagnetic resonance behavior at the microwave range. The permeability spectra are analyzed through the fittings with Landau-Lifshitz-Gilbert equation. From the fittings, both the dynamic magnetic anisotropy field and the damping factor increase, due to the enhanced spin-orbital coupling by Nd-doping.

“…Depending on the processing conditions, materials can be obtained with specific mechanical, magnetic and optical properties, microstructures, and surface textures. For example, Gan et al [21] investigated the structural properties of Cu2O-epitaxial films, Sun et al [22] determined the optical and electrical performance of thermochromic V2O3 thin films, Cao and Zhou [23,24] determined the magnetic properties of CoZrNb and FeNiCr films, Mirzaee et al [25] examined the surface textures of ZnO films, Rode et al [26] studied effects of deposition rate on surface roughness of Al films, Zenkin et al [27] investigated the thickness dependence of wettability and surface properties of HfO2 thin films, Han et al [28] explored the composition and structure of TiHxHe films, Gudla et al [29] investigated the microstructure evolution of AlZr and AlZrSi coatings during heat treatment processes, Kobata and Miura [30] examined the mechanical and thermal properties of TiCuZrNiHfSi thin films, Pshyk et al [31] analyzed the structural, morphological and tribo-mechanical properties of AlNTiB2TiSi2 coatings, and Mazur et al [32] investigated structural, optical, and micro-mechanical properties of (NdyTi1−y)Ox thin films produced by magnetron sputtering. Moreover, effects of the magnetron sputtering processing on the surface roughness of ultra-thin films are investigated in different studies [33][34][35][36][37].…”

Magnetron sputtering is a perfect technique for processing nanomaterials for engineering and medical applications. A material can be processed with specific mechanical properties, microstructure, and surface texture by controlling the parameters of magnetron sputtering. Therefore, studies should be conducted on investigating the processing conditions on the performance of nanomaterials processed by magnetron sputtering.In this study, effects of the processing force on performance of micro/nano-resonators produced by magnetron sputtering are revealed. The processing force is defined as the ratio of the sputtering power-tothe substrates traveling velocity. By comparing the substrate's traveling velocity to the deposition rate of the sputtered particles, relations are derived for the thickness and surface texture evolutions with the processing force. The coefficients of these relations are experimentally determined for mechanical resonators made of FeNiCr alloy. Then, the variations of the natural frequencies of these resonators with the processing force of magnetron sputtering and the deposition rate of the sputtered particles are depicted.It is demonstrated that special considerations should be given for the effects of the processing conditions when design mechanical resonators produced by magnetron sputtering.

“…1,2 Therefore, Co-Zr-Nb amorphous films have been widely studied as a good material for high-frequency applications such as noise suppressors, thin film transformers, magnetic inductors, etc. [3][4][5][6] Although Co-Zr-Nb amorphous films have been studied intensively from the fundamental point of view, [7][8][9] concentrations of Zr and Nb have been limited to amounts as small as possible. This is because magnetically soft films have been studied exclusively to improve high magnetization, high resistivity, and high resonance frequency.…”

This high-frequency magnetic properties of 250-nm-thick Co 85-(xþy) Zr 3þx Nb 12þy (x: 0-5.5, y: 0-11.0) amorphous films are examined as functions of Zr (x) and Nb (y) concentrations. Both x and y influence the high-frequency magnetic properties. In the case of x < 3.0 and y 5.0, each permeability spectrum appears, but increasing x and y decreases the ferromagnetic resonance (FMR) frequency from 1.20 GHz to 0.41 GHz and increases the effective damping constant from 0.15 to 0.43. For x ¼ 3.0 and y ¼ 8.2, although the permeability spectrum disappears, the effective damping constant is estimated to be approximately 0.82. In contrast, the high-frequency magnetic properties cannot be obtained for x ¼ 5.5 and y ¼ 11.0. Hence, appropriately selecting both Zr and Nb concentrations should effectively control the high-frequency magnetic properties. This finding should be of interest from the viewpoint of new thin film applications, such as microscopic electromagnetic compatibility (EMC), in which properly adjusting the permeability and FMR profiles is vital.
