  • Magnetic vortices confined to thin films gyrate with a dynamics determined by the vortex–core polarity, which switches when the gyration is fast enough. Fine-tuning these core-reversal oscillations reveals rich nonlinear behaviour, including commensurate and chaotic states.

  • Controlling chaotic behavior in spintronic devices is promising for signal-processing applications. Here, the authors unveil the symbolic patterns hidden in the magnetization dynamics of a nanocontact vortex oscillator and detail how to control chaos complexity with a single experimental parameter.

  • Applications of van der Waals magnetic systems are typically hampered by the low Curie temperature of van der Waals magnets. Here, Wang et al use molecular beam epitaxy to grow large films of Fe4GeTe2 with Curie temperatures over 500 K, and the film’s magnetic anisotropy can be tuned arbitrarily by controlling stoichiometry.

  • MoS2 is a promising two-dimensional candidate for opto-electronic and spintronic applications. Here, the authors report electrical spin injection and detection in a few-layered MoS2 channel, demonstrating that the spin diffusion length is at least 235 nm in MoS2conduction band.
