Peak collapse and shift of energy loss in a CoZrMo/SiO2 multi-layered thin-film core

Abstract The experimental result of the peak collapse and shift of the energy loss vs. frequency curve by the magnetic domain-wall motion was found in a CoZrMo/SiO 2 multi-layered thin film core. These properties have been theoretically predicted. It is explained that the experimental result is related to the chaotic motion of the magnetic domain wall, by using the power spectrum and the attractor in the phase space.
