Additive interfacial chiral interaction in multilayers for stabilization of small individual skyrmions at room temperature

Magnetic skyrmions can be stabilized at room temperature in cobalt layers sandwiched between heavy metal layers due to engineering of the interfacial Dzyaloshinskii–Moriya interaction.

Phase-locking of magnetic vortices mediated by antivortices

A magnetic vortex can be made to gyrate by a d.c. spin-polarized current. Researchers have now demonstrated the synchronization of four magnetic vortices through their interaction with antivortices. This work could lead to improved nanoscale microwave oscillators and a new way to study the behaviour of interacting solitons.

Mapping the spatial distribution of charge carriers in LaAlO₃/SrTiO₃ heterostructures

The interfaces between some perovskite oxide insulators show spectacular electronic properties, originating from the formation of an electron gas. The spatial extent of the electron gas is still under debate. Conducting tip atomic force microscopy is now used to show that, depending on the growth conditions, the high-mobility electron gas can extend to hundreds of micrometres or to just a few nanometres from the interface.

Giant tunnel electroresistance for non-destructive readout of ferroelectric states

As alternative technologies for non-volatile memory elements are looked at, the utilization of ferroelectric layers to read-write upon is seen as promising. However, it is plagued by several problems, including a destructive readout process. Now, by using a thin layer of BaTiO₃ put under intense strain, it has been shown possible to read out the polarization state of the material without destroying it.

Quasiparticle tunnel electroresistance in superconducting junctions

The non-volatile switching of tunnel electroresistance in ferroelectric junctions provides the basis for memory and neuromorphic computing devices. Rouco et al. show tunnel electroresistance in superconductor-based junctions that arises from a redox rather than ferroelectric mechanism and is enhanced by superconductivity.

Interface-induced room-temperature multiferroicity in BaTiO₃

With only a few known useful room-temperature multiferroics, other ways of achieving materials showing magnetism as well as electrical polarization are sought. The discovery that the ferroelectric BaTiO₃ also shows magnetism at room temperature at the interface with iron or cobalt marks a new approach to achieving multiferroic properties.
