  • The use of electric fields to control the magnetization of ferromagnetic materials could enable more efficient electronics. Lei et al.show that by applying lateral strain to a magnetostrictive nanowire with a piezoelectric, voltage-controlled gating of magnetic domain wall motion in the wire can be achieved.

  • In this manuscript, Finco et al demonstrate the use of a quantum magnetometer based on a single NV centre for all-optical imaging of antiferromagnetic (AFM) spin textures. By exploiting variations of the NV spin relaxation rate, they succeed in imaging AFM domain walls and skyrmions.

  • 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.

  • Where two oppositely magnetized regions meet, there is a so-called domain wall. Under the right conditions, this wall can be made to oscillate like a pendulum, suggesting a new approach to electronics.
