  • The collective gyrotropic excitation of an array of spin vortices has frequencies that depend on the polarities and chirality of individual vortices. This work demonstrates control of the spectral response of the system by tuning the excitation frequency or the external magnetic field.

  • Spin-waves offer the potential for devices with novel functionalities but controlling their propagation is proving challenging. Here, the authors use locally generated magnetic fields to show how spin-waves can be manipulated to realize a spin-wave multiplexer.

  • One of the attractions in studying oxide heterostructures is the unusual physical phenomena that they enable. It is now demonstrated that the enforced cation ordering in thin oxide superlattices leads to significantly enhanced magnetic ordering temperatures.

  • Although genetically bland, the posterior fossa group A subgroup of ependymomas, found often in infants and associated with poor prognosis, exhibit widespread epigenetic alterations, namely a CpG island methylator phenotype; these tumours are shown to be susceptible both in vitro and in vivo to various compounds that target epigenetic modifications, such as DNA methylation and H3K27 tri-methylation.

  • When superconductivity emerges in a thin superconductor grown on a ferromagnet, it does so in an array of interacting superconducting and normally conducting channels. Maria Iavarone and colleagues use scanning tunnelling microscopy to image how these channels form and interact.

  • Electrons confined in two dimensions, such as within ultra-thin semiconductor layers, lead to quantum-well states. Creating such states in metallic thin films, produces quantum wells that are spin-polarized or magnetic. This phenomenon may find applications in a new generation of magnetic recording media.

  • The astronomical event GW170817, detected in gravitational and electromagnetic waves, is used to determine the expansion rate of the Universe, which is consistent with and independent of existing measurements.
