  • 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.

  • The long-range magnetic order in an artificial crystal that exhibits emergent ferrotoroidicity on the mesoscale can be manipulated by an effective magnetic vortex field that is generated by a scanning process with a magnetic tip.

  • Controlling properties associated with antiferromagnetic states could unlock numerous applications, though this has long seemed elusive. Here, Wang et al. demonstrate how electric fields can manipulate the coupling between light and antiferromagnetic domains in a nonlinear optical interaction.

  • Memory B cells are important for protecting the host from pathogen rechallenge, but their properties and locations remain ill-defined. Here the authors show, using single-cell transcriptomics and repertoire analyses, that mouse spleen and bone marrow host distinct populations of isotype-switched memory B cells to potentially optimize for rapid recall responses.

  • The building blocks of the nanostructures observed on Drosophila corneas are determined, and then used to create artificial nanostructures with anti-reflective and anti-adhesive properties.
