The 514.5-nm radiation of an argon-ion laser served as the light source and the scattered light was frequency analyzed with

a (3 + 3)-pass tandem Fabry-Pérot interferometer selleck kinase inhibitor equipped with a silicon avalanche diode detector. Prior to the spectral scans, the sample was first saturated in a 0.7-tesla field applied along the symmetry axes of the stripes, which was then gradually reduced to zero. Spectra of the acoustic and spin waves were https://www.selleckchem.com/products/mm-102.html Measured in the p-p and p-s polarizations, respectively, and their dispersion relations mapped by varying the laser light incidence angle. Figure  1b,c shows typical Brillouin spectra recorded for the two excitations.

Figure 2 Phonon dispersion relations and mode displacement profiles. (a) Phonon dispersion relations of the Py/BARC magphonic crystal. Experimental and theoretical data are denoted by dots and solid lines, respectively. Red-dashed lines and magenta-dotted lines represent the simulated Rayleigh wave (RW) and Sezawa wave (SW) dispersions for the effective medium film on Si(001) substrate. The transverse (T) and longitudinal (L) bulk wave thresholds are represented

by respective green dot-dashed lines and blue short-dot-dashed lines. Measured Bragg gap opening

and the hybridization bandgap are indicated by a pink rectangle and a yellow band, respectively. z-components of the displacements of observed phonon modes at (b) q = π/a and (c) q = 1.4π/a. Figure 3 Magnon dispersion relations and magnetization profiles. (a) Magnon dispersion relations of the Py/BARC magphonic crystal. Experimental data are denoted by dots and theoretical data by lines, with solid (dotted) lines representing modes with relatively strong (weak) intensities. Measured bandgaps are shown as shaded bands, and Brillouin zone boundaries as vertical-dashed lines. The theoretical branches are labeled M1 to M3 and N1 to N5 (see Racecadotril text). The blue bars around q = 0 indicate calculated frequencies of the confined modes of an isolated Py stripe. (b) Cross section of magnetization profiles of the magnon modes within one Py stripe in a unit cell of the magphonic crystal at q = π/a. The dynamic magnetization vectors are represented by arrows, with their color-coded magnitudes. Results and discussion We will first focus our attention on the phononic dispersion. The measured phononic dispersion spectrum features a 1.0-GHz gap opening centered at 4.8 GHz at the Brillouin zone boundary, and a 2.2-GHz bandgap centered at 6.5 GHz.
