  • By increasing the number of degrees of freedom one can reduce overall number of devices required to perform logic operations. Here, Zhao, Zheng, Wang et al demonstrate a device using current direction, a vector property, allowing for the implementation of Boolean logic, including IMPLY in a single device, and further enabling the construction of a full adder with only two devices.

  • One challenge for spin-based electronics is the controlled and reliable switching of magnetization without magnetic fields. Here, Liu et al investigate a variety of compositions of CoPt, and determine the specific composition to maximize switching performance, potentially simplifying device design.

  • Ferroelectric hafnia-based thin films are promising for applications in memories and neuromorphic devices due to their robust ferroelectricity at reduced dimensions. Here, the authors demonstrate stabilization of the metastable orthorhombic phase in Hf0.5 Zr0.5O2 films by interface engineering with a hole doping mechanism.

  • Symmetry is an essential ingredient that governs numerous physical phenomena, including spin transport. Following this principle, spin current sources with a highly symmetric cubic structure are not expected to support anisotropic spin currents. Here, the authors demonstrate an anomalous spin current anisotropy in a cubic noncollinear antiferromagnet Mn3Pt by exploiting the combination of conventional and magnetic spin-hall effects.

  • Spin–orbit torque in heavy metal/ferromagnet heterostructures is promising for all-electric control of magnetic memory, but has so far required an additional symmetry breaking in the design to switch perpendicular magnetization. Instead, a low symmetry at the interface can give rise to out-of-plane spin torque and switch the magnetization deterministically.
