  • Domain walls in ferroelectrics can lead to phenomena different from the bulk. Here the authors achieve polarization control of charged domain walls in improper ferroelectrics by magnetic fields that convert neutral into charged domain walls.

  • Magnetic metamaterials can be designed to provide models of frustrated systems that allow theoretical predictions to be experimentally tested. Here the authors realise a 2D XY model with dipolar interactions and find behaviour consistent with predictions of a low-temperature ordered state.

  • Both extrinsic and intrinsic factors determine the properties of ferroic materials and are difficult to disentangle. This study on artificial crystals of planar nanomagnets with well-defined, tuneable magnetic interactions unveils the intrinsic correlations between microscopic interactions and macroscopic properties such as the domain size and morphology or the domain-wall mobility.
