  • Spin-polarized carriers could show an extra Hall component when moving through certain real-space topological spin textures. Here, He et al. report an exchange bias experienced by the topological spin textures living at the interface between a topological insulator and an adjacent antiferromagnet, suggesting a chiral spin texture is induced.

  • Mechanisms allowing electrical manipulation of magnetic material possess potential applications in low power memory and sensor technologies. Here, the authors demonstrate the control of magnetic characteristics via voltage-driven migration of oxygen across a GdOx/Co interface, well into the bulk of the cobalt.

  • The perpendicular Néel order in a collinear antiferromagnetic insulator—chromium oxide—can be switched by 180° via the spin–orbit torque with a low current density of 5.8 × 106 A cm−2 and read out via the anomalous Hall effect.

  • Hydrogen from surface-based electrolysis is implicated in the operation of high-speed magneto-ionic devices. Functionalizing this discovery, a new family of potentially high-speed, high-efficiency ionic devices is born.

  • Direct observation of ionic motion in buried metal/oxide interfaces and its correlation with physical properties is a challenging task. Here, the authors observe oxygen migration in a model system with controllable positive exchange bias, due to the redox-driven formation of a ferromagnetic interfacial layer.

  • Many complex oxides already have rich functional behavior but oxide heterostructures can exhibit new emergent properties. Yi et al. show that LSMO/SIO superlattices have a reversible electric-field-controlled structural phase transition that is not present in the constituent materials.
