The back‐cover picture, referring to article number 2000011 by Morteza Mohseni et al., shows a spin‐wave waveguide whose magnetization is excited by the microwave antenna on top. The spin‐wave dynamics are probed via the Brillouin light‐scattering spectroscopy (BLS) laser probe. The spheres demonstrate the scattering of a photon ( w p ) to two counter‐propagating magnons ( w p /2). This is studied by the authors via the parametric pumping of spin‐waves using a microwave driven stripline probed by the BLS spectroscopy.
