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.

超薄钇铁石榴石波导中自旋波传播的参数生成

背面图片参考了Morteza Mohseni等人的商品编号2000011，显示了一个自旋波波导，其磁化强度被顶部的微波天线激发。自旋波动力学通过布里渊光散射光谱（BLS）激光探头进行探测。球体显示了光子（w _p）向两个反向传播的马农（w _p / 2）的散射。作者通过使用由BLS光谱仪探测的微波驱动的带状线通过自旋波的参数泵浦研究了这一点。
