Tailoring ferromagnetic resonance properties of cobalt nanowires: effects of shape and magnetocrystalline anisotropies
Martín I. Broens, Eduardo Saavedra, Enzo Fabrizio Pusiol, Noelia Bajales, Juan Escrig
Abstract
Distinct magnetic states arise from shape and magnetocrystalline anisotropies, influencing resonant mode types. Nanowires with flower-type states show edge and fundamental modes, while those with vortex states exhibit azimuthal and gyrotropic modes.
