“…Hence, the use of phase interference including MCs with FV SWs is significantly promising. However, only a few experimental studies [29] have researched MCs using FV SWs, although many experimental reports have described two modes-specifically, surface SWs (S SWs) [30][31][32][33][34][35] and backward volume SWs (BV SWs) [3,29,[36][37][38]. This is mainly because of the significant noise in the FV SW configuration, which makes it difficult to observe a magnonic band gap (MBG) in experiments that employ low damping materials (yttrium iron garnets, YIG) as waveguides.…”

One-Dimensional Magnonic Crystal With Cu Stripes for Forward Volume Spin Waves

et al. 2019

A one-dimensional magnonic crystal for forward volume spin waves (FV SWs) is demonstrated using eight pairs of Cu stripes fabricated on a 1-mm wide × 14-mm long × 10.2-µm thick yttrium iron garnet (YIG) waveguide and a SW absorber of 30-nm-thick Au film. The development of this crystal is challenging due to strong spectral oscillations caused by edge reflections and process difficulties associated with YIG magnonic crystals. A magnonic band gap with a depth of −4.6 dB is observed at a frequency of 1.80 GHz for a FV SW excited by a 50-µm-wide microstrip line, which is in good agreement with simulation results using three-dimensional modeling in the radio frequency region. The obtained performance is illustrated by plotting the depth of the respective band gaps vs the pair number of the stripes. This value is compared with that obtained in previous studies.

“…If the interval is large ( → ∞), we can assume that the waves in the FF and the FE are not coupled. In this case, the dispersion relation for the surface MSW at 0 ≪ 1 can be represented in the following form [17,18]:…”

The spectral characteristics of the hybrid spin-electromagnetic waves in multiferroic layered structure magnonic crystalferroelectric were theoretically and experimentally investigated. The main features of the band gaps formation in such structure were compared to the case of a single magnonic crystal. The possibility of the band gaps characteristics control with varying of electric field is demonstrated.

“…In the splitter's leg, the mode profile in the MSSW and BVMSW configurations is clearly that of the fundamental mode (n ¼ 1). From the asymmetry of the spin wave amplitude profile in the splitter's arms, however, we deduce that one-to-many mode splitting 25,26 has taken place, whereby an asymmetric n ¼ 2 mode is propagating alongside the original fundamental mode. This is in agreement with the findings of Clausen et al…”

We demonstrate a magnonic beam splitter that works by inter-converting magnetostatic surface and backward-volume spin waves propagating in orthogonal sections of a T-shaped yttrium iron garnet structure. The inter-conversion is enabled by the overlap of the surface and volume spin wave bands. This overlap results from the demagnetising field induced along the transversely magnetised section(-s) of the structure and the quantization of the transverse wave number of the propagating spin waves (which are therefore better described as waveguide modes). In agreement with numerical micromagnetic simulations, our Brillouin light scattering imaging experiments reveal that, depending on the frequency, the incident fundamental waveguide magnonic modes may also be converted into higher order waveguide modes. The magnonic beam splitter demonstrated here is an important step towards the development of parallel logic circuitry of magnonics.
