  Ultrafast push for counterintuitive spintronics

  Current-inducing switching of magnetization is crucial for future magnetic data processing technologies, but switching it with speed and energy efficiency remains challenging. Using femtosecond optical pulses, instead of conventional charge currents, is found to make spintronics not only ultrafast but also counterintuitive.

  Optically induced ultrafast magnetization switching in ferromagnetic spin valves

  The authors demonstrate optically induced ultrafast magnetization reversal taking place within less than a picosecond in rare-earth-free spin valves of [Pt/Co]/Cu/[Co/Pt].

  Chiral-phonon-activated spin Seebeck effect

  The authors report spin current generation in a metallic layer adjacent to a non-magnetic chiral hybrid organic–inorganic perovskite when subjected to a thermal gradient, and attribute this to chiral phonons possessing angular momentum.

  All-optical switching of magnetization in atomically thin CrI₃

  The authors use circularly polarized light pulses to trigger all-optical magnetization switching in an atomically thin ferromagnetic semiconductor. The switching process is related to spin angular momentum transfer from photoexcited carriers to local magnetic moments.

  Creation of moiré bands in a monolayer semiconductor by spatially periodic dielectric screening

  The moiré pattern that is formed between well-aligned graphene and hexagonal boron nitride can modify the properties of WSe₂ (placed close by without intentional angle alignment), leading to the formation of a mini Brillouin zone and the folding of the bands in WSe₂.

  Persistent optically induced magnetism in oxygen-deficient strontium titanate

  Strontium titanate is widely studied for the myriad of phenomena that are known to occur in the vicinity of its surface. It is now shown that light can be used to induce magnetism in oxygen-deficient crystals of SrTiO₃.
