  • Solving a task of optimal route search may be challenging for conventional algorithms. Here, authors use tunable random signals from magnetic tunnel junctions to improve a probabilistic greedy Traveling Salesman Problem solver to better balance exploration and efficiency, and make it applicable for larger problems.

  • Skyrmions are objects with whirled magnetization protected by their topology that can be created by different means, however, without control of their position. Here, the authors present a method exploiting x-rays to create skyrmions at the beam position allowing for creation of artificial skyrmion lattices.

  • Strong magnetic interfacial coupling in van der Waals heterostructures provides a new platform for discovering novel physics and effects. Here, the authors report the formation of skyrmion lattice in the WTe2/Fe3GeTe2 van der Waals heterostructure and a Dzyaloshinskii–Moriya interaction with a large energy density of 1.0 mJm−2.

  • Antiferromagnetic materials are potentially useful for spintronic applications. Here, the authors report high thermoelectric power value of 390 μV/K Seebeck coefficient in IrMn-based half magnetic tunnel junctions at room temperature.

  • Recently, significant progress has been made in higher harmonic generation of spin waves in magnetic materials, but it remains challenging to probe the coherence. Here, Lan, Liu et al observe the higher-harmonic spin-wave generation induced by static edge spin textures in a soft ferromagnetic film, and probe the coherence of higher harmonic generation.

  • 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.

  • Ferromagnet/spacer/ferromagnet sandwiches have been studied extensively, and used in a variety of spintronic devices. Here, Zhou et al. create an all anti-ferromagnetic sandwich of Fe2O3/Cr2O3/Fe2O3, and demonstrate strong orthogonal coupling between the top and bottom Fe2O3 layers.

  • Spin-pumping experimental technique where a DC or AC spin current is generated, and typically transferred to a heavy metal layer where it can be detected via electrical measurements. While well established in conventional materials, coherent spin-pumping in van der Waals magnetic materials is challenging due to the low damping and high-quality interface requirements. Here, Xu et al demonstrate coherent spin pumping in the van der Waals magnet Cr2Ge2Te6.
