摘要: Abstract A multifractal analysis for bulk spin waves propagating in quasiperiodic magnetic multilayers is carried out the magnetostatic regime. Numerical results are obtained by considering their propagation these artificial structures arranged Fibonacci, Thue–Morse and double-period sequences. An behavior of scaling exponent δ (the diffusion constant spectra) versus in-plane wavevector K also done, leading to interesting results. The spectra based on ferromagnet crystal Fe antiferromagnet MnF 2 .
