    Ferromagnetic systems produced by the transition metal doping of semiconductors may be used as components of spintronic devices. Here, a new ferromagnet, Li1+y(Zn1-xMnx)As, is prepared in bulk quantities and shown to have a critical temperature approaching 50 K.

    Flux-closure patterns are rarely observed in ferroelectric materials and almost exclusively form at the nanoscale. McQuaidet al. report mesoscopic dipole closure patterns formed in free-standing single-crystal lamellae of BaTiO3, thought to result from an unusual set of experimental conditions.

    Single-molecule magnets could be useful for the development of spintronic devices. Here single-molecule magnets are encapsulated in carbon nanotubes without affecting the properties of the guest molecules, which may be useful in the development of spintronic or high-density magnetic storage devices.

    Light–matter interactions can be used to manipulate magnetization in solids, but light-controlled magnetization vector motion has not been demonstrated. Here, two-dimensional magnetic oscillations in NiO are manipulated with optical pulses leading to vectorial control of magnetization by light.

    In molecular spintronics, the spin state of a molecule may be switched by changing the molecular structure. Here, the spin of a single-molecule magnet is switched by applying an electric current using a scanning tunnelling microscope, which may aid in information coding at the single-molecule level.

    The imaging of magnetic domains in three-dimensional solids has been hampered by a lack of suitable methods. The authors show that Talbot-Lau neutron tomography is capable of visualizing the domain structure of an iron silicide bulk crystal.

    The spatial scale over which metal–insulator transitions happen is not known, despite the importance of this phenomenon in basic and applied research. The authors show that in chromium-doped V2O3, with decreasing temperature, microscopic metallic domains coexist with an insulating background.
