“…18,19 In the domain of magnonics, FEBID allows for the realization of 3D magnonic crystals [20][21][22] and magnonic conduits with graded refractive index. 23 However, the magnetic parameters of individual nanoelements are often poorly known and can hardly be assessed by local optical † Electronic supplementary information (ESI) available: Supporting Note 1, probe techniques, such as Brillouin light scattering (BLS) 24 and magneto-optical Kerr microscopy, 25 having a spatial resolution limit of about 300 nm. For resolving the magnetization dynamics at GHz frequencies on the length scale of a few tens of nm more sophisticated techniques are required.…”

“…Although spin waves can be guided along curved waveguides, this typically results in additional losses. [310][311][312][313] Although special waveguide designs alleviate the issue to some extent, [314][315][316][317] the routing capabilities of spin waves at the nanoscale are limited, with repercussions on the spin-wave devices layout and scalability.…”

This paper provides a tutorial overview over recent vigorous efforts to develop computing systems based on spin waves instead of charges and voltages. Spin-wave computing can be considered as a subfield of spintronics, which uses magnetic excitations for computation and memory applications. The tutorial combines backgrounds in spin-wave and device physics as well as circuit engineering to create synergies between the physics and electrical engineering communities to advance the field towards practical spin-wave circuits. After an introduction to magnetic interactions and spin-wave physics, all relevant basic aspects of spin-wave computing and individual spin-wave devices are reviewed. The focus is on spin-wave majority gates as they are the most prominently pursued device concept. Subsequently, we discuss the current status and the challenges to combine spin-wave gates and obtain circuits and ultimately computing systems, considering essential aspects such as gate interconnection, logic level restoration, input-output consistency, and fan-out achievement. We argue that spin-wave circuits need to be embedded in conventional CMOS circuits to obtain complete functional hybrid computing systems. The state of the art of benchmarking such hybrid spin-wave--CMOS systems is reviewed and the current challenges to realize such systems are discussed. The benchmark indicates that hybrid spin-wave--CMOS systems promise ultralow-power operation and may ultimately outperform conventional CMOS circuits in terms of the power-delay-area product. Current challenges to achieve this goal include low-power signal restoration in spin-wave circuits as well as efficient spin-wave transducers.

“…The possible stable or metastable magnetic configurations are determined by bulk interactions (exchange stiffness, static magnetization, bulk magnetocrystalline anisotropy), state of the surfaces (surface magnetocrystalline anisotropy) and by the geometry of the system [11,12]. The latter factor can be designed in the fabrication process.…”

Nanoscale magnetic systems have been studied extensively in various geometries, such as wires of different cross-sections, arrays of wires, dots, rings, etc. Such systems have interesting physical properties and promising applications in advanced magnetic devices. Uniform magnetic nanowires are the basic structures which were broadly investigated. However, some of their dynamical properties, like: (anti)crossing between the spin wave modes and impact of the magnetic field on spin wave spectrum, still need to be exploited. We continue this research by investigation of the spin wave dynamics in solid Ni nanowire of the circular crosssection. We use two approaches: semi-analytical calculations and numerical computations based on finite element method. We solve coupled Landau-Lifshitz and Maxwell equations and consider both magnetostatic and exchange interactions. We identify the dispersion brunches and its (anti)crossing by plotting the spatial profiles of spin wave amplitudes and magnetostatic potential. We also check how we can tune the spectrum of the modes by application of the external magnetic field and how it affects the modes and their dominating type of interaction.
