  • Injecting spin-polarized current into a ferromagnetic thin film via a nanocontact is expected to generate a radially-symmetric spin wave soliton. Here, the authors use time-resolved x-ray microscopy and micromagnetic simulations to demonstrate the occurrence of p-like symmetry associated with non-uniform magnetic fields in the nanocontact region.

  • Spin-Hall nano-oscillators are attractive for spintronics due to their high efficiency and simple layout. Here, the authors demonstrate synchronization of these oscillators to external microwave signals, opening up new possibilities for spintronic applications.

  • Spin current-induced quasi-equilibrium state of magnon gas described by the Bose–Einstein statistics has been previously theoretically predicted. Here, authors experimentally show that the spin current-driven magnon distribution can be treated thermodynamically, and potentially form a Bose–Einstein condensate.

  • A spin torque nano-oscillator consists of a free magnetic layer and a reference magnetic layer. Many works have examined the behaviour of droplet solitons in the free magnetic layer. Here, Jiang et al. extend this to pair of droplet solitons, with one in the free layer and one in the reference layer.
