  • The close relationship between crystal structure and electric polarization in ferroelectrics means that strain strongly influences their properties. The demonstration of how strain gradients leading to a higher-order effect, flexoelectricity, can be used to rotate electric polarization in thin films indicates new ways of controlling piezoelectricity by purely mechanical means.

  • Electron beam manipulation is important for their application in microscopes, lithography instruments, and colliders. Here the authors report a wafer scale, self-assembled, microcoil electrically-driven magnetic charge particle optic device that can be implemented into different configurations for controlling of electron beams.

  • Recently, there has been great interest in studying plasmons in strange metals characterized by linear-in-temperature electrical resistivity. Schultz et al. report an EELS in transmission study of plasmons in Sr2RuO4, revealing unrenormalized behavior explained by resilient quasi-particles at high plasmon energy.

  • Holographic vector-field electron tomography reveals the three-dimensional magnetic texture of Bloch skyrmion tubes in FeGe at nanometre resolution, including complex three-dimensional modulations and fundamental skyrmion formation principles.

  • Characterizing plasmonic coupling has proven elusive. Here, the authors obtain a spectrally resolved deflection map related to a focused electron beam, which has excited a surface plasmon resonance, and relate this deflection to the spectral component of the induced electric and magnetic fields pertaining to the mode.

  • Skyrmions and anti-skyrmions are magnetic textures that have garnered much interest due to their stability. Here, Jena et al demonstrate the existence of fractional spin textures at the edges of Heusler alloy sample, which can have continuous variable topological charges.
