Effect of annealing temperature on surface morphology and ultralow ferromagnetic resonance linewidth of yttrium iron garnet thin film grown by rf sputtering

Directional Field-Dependence of Magnetoimpedance Effect on Integrated YIG/Pt-Stripline System

“…The peaks of YIG (444) and GGG (444) overlap due to their good lattice match, and no evidence of polycrystalline YIG is verified, meaning that textured YIG layer is formed in the growth direction of [111]. Our findings are in accordance with results previously reported in the literature for similar heterostructures [32][33][34][35]. Although the XRD pattern shows evidence of the YIG crystallization, which is also corroborated from the comparison with the literature, we yet may employ quasi-static magnetic technique to further characterize the YIG phase after the annealing.…”

Assessing the relaxation mechanisms contributions on magnetoimpedance effect in YIG/W bilayers

“…Specifically, the peak observed at 2θ ≈ 51.1 • is associated with the GGG (444) diffraction pattern substrate (ICSD 9237). From our concern, the peak associated with YIG (111) is located at 2θ ≈ 50.9 • (ICSD 60167) [32][33][34], which is overlapped due to the proximity with the high-intensity GGG (444) peak. Moreover, no evidence of polycrystalline YIG is verified.…”

“…It suggests the post-annealing conditions were not able to produce flat films. As a consequence, these imperfections may directly contribute to the linewidth broadening observed from the dynamic magnetic characterization, as we are going to check in the following [30,33,34,[36][37][38].…”

Study of growth and broadband FMR spectroscopy in PLD grown Y3Fe5O12/Gd3Ga5O12 thin films

“…In order to study the angular dependence of resonance field, line width, and damping, we choose our best quality film, i.e. 100 nm with least damping and inhomogeneous broadening and rotated the sample fixed on CPW from φ = 0 • (film surface is parallel to H) to φ = 90 , where M s is the saturation magnetization taken to be 123.39 emu cc −1 for 100 nm thin film [38] and H u is the anisotropy field [28,39]. The inset image of figure 6(b) shows frequency dependent K u variation, which clearly shows an increase of anisotropy with increasing frequency.…”
