  • Realizing strong magnon-phonon coupling (i.e., magnon-polaron formation) is challenging and typically involves a material or cavity that confines the magnon to a small volume. Here, by combining a YIG film with a ZnO acoustic resonator, Künstle and coauthors achieve magnetic field tuneable magnon-polarons in a virtually infinite magnetic film, and succeed in observing Rabi-like oscillations in the time domain.

  • There has been considerable interest in using magnons for information processing. Such ‘magnonic’ devices will require magnetic patterning analogous to the lithographic patterns of integrated circuits. Here, Levati, Vitali and coauthors present one possible approach to this, demonstrating laser induced changes in the perpendicular magnetic anisotropy of Yttrium Iron Garnet.

  • A repeater takes an input signal and retransmits is, and a vital component for extending the range of signals. Here, Wang et al. demonstrate a magnon repeater, based on the bistable switching between low and high amplitude spin-waves.

  • Skyrmions are topological spin textures, which have been proposed as useful for a diverse array of applications. One such proposal is to make use of a skyrmion’s thermally activated Brownian-like diffusive motion for unconventional computing and true random number generation. Here, Dohi et al show how, in a synthetic antiferromagnet, this diffusive motion can be significantly enhanced.

  • The field of magnonics studies the dynamic excitations of a magnetically ordered material. This Review surveys coherent magnonics, discussing the design of spin-wave devices and the use of magnon Bose–Einstein condensates to enable a broad range of applications.

  • Inverse design is a recent development in photonics, where by locally controlling the refractive index in a matrix, nearly any information processing functionality can be achieved. Here, Wang et al. present a scheme for inverse design for spin-waves, magnons, which have a variety of unique advantages, such as short wavelength, and large non-linearity.

  • Magnetic domain walls can modulate spin-wave transport in perpendicularly magnetized channels, while magnon spin current can drive domain wall motion in the bi-doped yttrium iron garnet channel device.

  • Tin Aung, Christopher Hammond and colleagues report the results of a large genome-wide association study of intraocular pressure. They identify four new loci associated with this trait and show that three of these loci are associated with risk of primary open-angle glaucoma.

  • An analysis of 16 health-related quantitative traits in approximately 350,000 individuals reveals statistically significant associations between genome-wide homozygosity and four complex traits (height, lung function, cognitive ability and educational attainment); in each case increased homozygosity associates with a decreased trait value, but no evidence was seen of an influence on blood pressure, cholesterol, or ten other cardio-metabolic traits.

  • This work presents a comprehensive study of the dynamics of coupled magnetic vortex cores in a multilayer spin valve structure. It is shown that tuning the conservative and non-conservative forces by modulating the applied dc current and magnetic field leads to previously unconsidered complex orbits of the vortex cores and a possible application in reservoir computing is proposed.
