  • 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.

  • Signal processing by time reversal has thus far only been realized through nonlinear mechanisms. The authors describe an all-linear, and thus low-power, time-reversal process based on frequency inversion in a dynamically controlled artificial periodic structure, a dynamic magnonic crystal.

  • The collective gyrotropic excitation of an array of spin vortices has frequencies that depend on the polarities and chirality of individual vortices. This work demonstrates control of the spectral response of the system by tuning the excitation frequency or the external magnetic field.

  • A new method to form Bose–Einstein condensates of quasiparticles based on the rapid decrease in the phonon temperature was proposed and shown experimentally.

  • In contrast to real atoms, Bose–Einstein condensation of quasi-particles does not require low temperature, but is obtained via external pumping. Here, the authors show an unexpected transitional dynamics of a Bose–Einstein condensate of magnons due to a nonlinear evaporative supercooling mechanism.

  • By modulating the dimensions of magnonic crystals, their transmission properties in the microwave regime may be tuned and so applications including information processing are anticipated. The authors here show reflection-less spin-wave propagation may be realised in a width-modulated waveguide.

  • Fast and energy-efficient control of magnon transport in magnonic crystals is one of the main challenges of modern magnonics. High performances for voltage control are expected but have so far only been predicted theoretically and investigated numerically. In this paper, the authors report of the first experimental realization of voltage-controlled magnon currents in a dynamic electromagnonic crystal.
