  • Skyrmions emerging from complex order offer superior stability and functionality for data processing and storage, but creating such objects is intrinsically difficult. Homochiral electric and antiferromagnetic structures at the domain walls of a room-temperature multiferroic are now observed.

  • It has been suggested that the strange metal phase in cuprates stems from a quantum critical point slightly above optimal doping. By resonant x-ray scattering in two cuprate families in a wide doping range, Arpaia et al. show that charge density fluctuations could be associated with this quantum critical point.

  • Spin-crossover molecules offer a potential route towards molecular spintronics, but retaining the bistability of the spin state upon surface deposition is challenging. Here, the authors study the spin-crossover behaviours of an Fe(II) complex deposited on graphite, determining the scale limit at which cooperative spin switching becomes effective.

  • Controlling stoichiometry and electronic reconstruction at the interface of transition metal oxide heterostructures offers a new way to tune their unique properties, leading to behaviors distinct from the bulk components. Using atomically resolved scanning transmission electron microscopy, element specific x-ray resonant magnetic reflectivity and x-ray magnetic circular dichroism, we have demonstrated that the presence of local oxygen deficiency across the interface and charge transfer to the empty conduction band of SrTiO3 at the interface are the primary drivers for the modified interfacial magnetism in the manganite thin films and Ti3+ induced ferromagnetism at the La0.7Sr0.3MnO3/SrTiO3 interface.

  • A new form of charge ordering is observed in a cuprate superconductor. At low doping, a fully rotationally symmetric ordering appears before becoming locked to the Cu–O bond directions at high doping. The link between charge correlations and fermiology give a perspective on the phase diagram.
