  • The disordering of the vortex lattice in a type-II superconductor is widely perceived to underpin unusual peaks in the temperature and field dependence of critical current. By contrast, here Toft-Petersen et al. find an order-disorder transition in a superconducting vanadium sample that is unconnected with peaks observed in critical current.

  • In magnetoelectric materials, the magnetization can be controlled by the application of an electric field, making it comparatively easy to switch magnetization, which is attractive for data storage and other proposed devices. Unfortunately, the effect in single-phase materials is typically fairly weak. Here Fogh et al. demonstrate a two orders of magnitude enhancement of the magnetoelectric coupling in LiNi0.8Fe0.2PO4 compared to the parent compounds.
