“…Self-exciting positivefeedback spin-wave systems, often termed spin-wave active rings, are used for this purpose [225,226]. The basis for such an active ring is a dispersive spin-wave waveguide with exciting and receiving antennas connected together via a variable-gain electrical feedback loop (see figure 6(a)).…”

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...

“…The propagation both of solitons and of two-dimensional nonlinear quasi-stable excitations called "bullets" (see Fig. 3), has been extensively studied in magnon systems [27][28][29][108][109][110]. The robustness of these waveforms gives them interesting potential as information bearers in magnon spintronic devices.…”

Presented here is an introduction to magnon spintronics, the emerging field of research concerned with structures and devices which involve the interconversion between electronic spin currents (spin currents carried by electrons) and magnon currents (spin angular momentum fluxes which do not involve the motion of charged carriers). Aimed at the nonexpert reader, the text reviews fundamental and applied aspects of magnonics and examines how the study of the interplay between magnonic and electronic spin transport both shines a light on new physics, and opens doors to new technologies.

“…In one dimensional finite spin chains for example [2] one can find envelope functions corresponding to one or more solitons. Recently both bright and dark solitons have been observed in feedback rings [3] and chaotic solitary spin wave pulses have also been produced [4]. A second area of research has focused on nonlinear magnetic motions driven by currents [5,6] or on chaos produced by a driving magnetic field [7].…”
