On the spin wave multifractal spectra in magnetic multilayers

The multifractal properties of spin wave bandwidths in quasiperiodic magnetic multilayers are studied. The profiles of the bandwidths are analyzed and the f(α) function is calculated for different values of the dimensionless in-plane wave vector kxa and for four different sequences: Fibonacci, double-period, Thue–Morse and Rudin–Shapiro. We note that the f(α) spectra is qualitatively the same for different values of kxa
