  • Magnetic systems can exhibit flat bands where the magnon bands have little to no energy dispersion. Here, Luo, Chen, and coauthors show the nearly flat bands of the van der Waals antiferromagnet, CrOCl, and demonstrate quasi one-dimensional magnon transport.

  • Spin transport properties of magnetically ordered materials have been well studied. Here, the authors report an anomalous spin signal exhibiting spin transport over 480 microns in the frustrated hyperkagome magnetic insulator Gd3Ga5O12.

  • The anisotropic electrical and optical response of materials has allowed for the development of variety of sensors, memories and other interesting devices. Here, Qi et al turn their attention to the van der Waals antiferromagnetic insulator CrPS4, and demonstrate a very large, electrically tunable anisotropy in magnon transport, and present a multibit read-only memory based on this anisotropy.

  • A major challenge in magnon based approaches to information processing lies in developing valves to allow or supress the magnon signal. Here, Chen et al demonstrate a van der Waals magnet based magnon valve which can be tuned electrically over an exceptionally wide range.
