  • External driving of Rabi oscillations is a first step in the coherent manipulation of spin systems. Here the authors use ultrafast optical pulses to produce classical Rabi oscillations in ferromagnetic CoFeB, enabling the exploration of coherent phenomena in dense ferromagnetic ensembles.

  • In most metals the optical Hall effect is very small at visible wavelengths, and usually can only be observed at low frequencies. Here, Am-Shalom et al present a technique involving a large amplitude modulation of the external magnetic field, allowing for the measurement of the optical Hall effect in a range of metals at visible wavelengths.

  • Spin manipulation in memory devices typically requires large electrical currents, limiting performance. Here the authors demonstrate magnetization switching in ferromagnetic films by depositing chiral molecules, making use of a proximity effect without needing magnetic or electric fields.

  • Fe3Sn2 hosts very robust magnetic skyrmions, stabilized via frustration, rather than the typical Dzyaloshinskii-Moriya interaction. Here, Bernstein et al. using a spin torque skyrmion resonance, detect key features of this skyrmion phase in the observed resonances, and find that this can be tuned via an applied current.
