“…In particular, considerable attention has attracted investigations of magnonic crystals with defects [31][32][33][34][35], topological and nonreciprocal phenomena in magnonic crystals [36][37][38][39][40][41][42][43][44], linear and nonlinear spin-wave dynamics in coupled magnonic crystals [45][46][47], and the formation and propagation of solitons [48][49][50][51]. Besides one-dimensional magnonic crystals [81][82][83][84][85][86][87][88][89][90][91][92][93][94][95][96][97][98], two-dimensional magnonic crystals have been intensively studied experimentally while three-dimensional magnonic crystals [78][79][80] are investigated theor etically.…”

IntroductionThis article focuses on a selection of results in the field of magnonic crystals obtained within the last decade in our group. Special attention is devoted to the application of magnonic crystals in data processing and information technologies. Because of the large number of achievements in the field, it is unavoidable that many important results are excluded from this article. Therefore, we would like to direct the reader's attention to excellent reviews devoted to different aspects of magnonic crystals: spin-wave dynamics in periodic structures for microwave applications [1, 2], Brillouin light scattering (BLS) studies of planar metallic magnonic crystals [3], micromagnetic computer simulations of width-modulated waveguides [4], photo-magnonic aspects of antidot lattices studies [5], theoretical studies of one-dimensional monomode waveguides [6], and reconfigurable magnonic crystals [7]. The results presented in the current review were already partially presented in our own reviews of yttrium iron garnet (YIG) magnonics [8] and magnon spintronics [9] as well as in book chapters on dynamic magnonic crystals [10] and magnon spintronics [11].The article is organized in the following way: In the introduction we describe the field of magnon spintronics and discuss the role of magnonic crystals in it. The next section 2 is devoted to the properties of spin waves in thin planar films and waveguides, to the magnetic materials commonly used in the field, and to the methods of spin-wave excitation and detection. Sections 3 and 4 are devoted to the study of physical phenomena taking place in static and dynamic magnonic crystals, respectively. The application of magnonic crystals for magnonbased processing of analog and digital data is discussed in section 5. Specifically, static magnonic crystals can be used as passive elements, like microwave filters, resonators or delay lines for microwave generation. Reconfigurable and dynamic magnonic crystals are promising as active devices performing, for example, tunable filtering, frequency conversion or time reversal. In the final section we briefly summarize the results. Magnon spintronics: from electron-to magnon-based computingA disturbance in the local magnetic order can propagate in a magnetic material in the form of a wave. This wave was first predicted by Bloch in 1929 and was named spin wave since AbstractMagnons (the quanta of spin waves) propagating in magnetic materials with wavelengths at the nanometer-scale and carrying information in the form of an angular momentum can be used as data carriers in next-generation, nano-sized low-loss information processing systems. In this respect, artificial magnetic materials with properties periodically varied in space, known as magnonic crystals, are especially promising for controlling and manipulating magnon currents. In this article, different approaches for the realization of static, reconfigurable, and dynamic magnonic crystals are presented along with a variety of novel wave phenomena discovered in these cryst...

“…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.

“…The SW waveguides, multiplexers [20], coupled waveguides with or without exploitation of periodic gratings [21][22][23] have been investigated as basic units for processing information, some of them were demonstrated experimentally. Most of these studies deal with the in-plane SW propagation, but control of SW propagation in out of-plane direction is also promising for applications, although an area of 3D magnonics still remain unexplored [24].…”

The possibility to generate short spin waves (SWs) is of great interest in the field of magnonics nowadays. We present an effective and technically affordable way of conversion of long SWs, which may be generated by conventional microwave antenna, to the short, sub-micrometer waves. It is achieved by grating-assisted resonant dynamic dipolar interaction between two ferromagnetic layers separated by some distance. We analyze criteria for the optimal conversion giving a semi-analytical approach for the coupling coefficient. We show by the numerical calculations the efficient energy transfer between layers which may be either of co-directional or contra-directional type. Such a system may operate either as a short spin wave generator or a frequency filter, moving forward possible application of magnonics. permalloy (Py)-CoFeB bilayer separated by a nonmagnetic spacer, with Py layer decorated with a grating. We show, that it is possible to achieve complete SW power exchange between the layers, if the structure is optimized for resonant, phase-matched interaction of a proper magnitude. We tested influence of damping on the SW energy exchange between layers, and show that the effect can be optimized by increasing grating thickness. We propose such a system to be a simple and efficient transducer for generation of short SWs in Py from long SWs in CoFeB, which allows to transfer the SW signals in the vertical direction, and also to exploit it as a narrow band filters for future magnonic devices.
