摘要：

In this work, we study experimentally by broadband ferromagnetic resonance measurements, the dependence of the spin-wave excitation spectra on the magnetic applied field in CoFeB meander-shaped films. Two different orientations of the external magnetic field were explored, namely parallel or perpendicular to the lattice cores. The interpretation of the field dependence of the frequency and spatial profiles of major spin-wave modes were obtained by micromagnetic simulations. We show that the vertical segments couple the horizontal sections of the structure and support the in-phase and out-of-phase spin-wave precession amplitude for several magnetic modes. The investigated structures could potentially be used for the design of tunable metasurfaces or in magnetic memories based on meandering 3D magnetic films.
