The spin of an electron precesses in the molecular field of a magnetic thin film, as explored by Coriolan Tiusan, Michel Hehn, and co‐workers in article number 2000470. In the presence of a high molecular field, precession is ultra fast. The front cover image shows a representation of the spin precession (colored arrows) of an electron (gray balls) in the molecular field (pastel arrows) of a ferromagnetic material (blue balls).

分子场：磁性薄膜分子场中的低能自旋进动（Ann。Phys。2/2021）

电子的自旋在磁性薄膜的分子场中进动，正如科里奥兰·图桑（Coriolan Tiusan），米歇尔·海恩（Michel Hehn）和他的同事在文章编号2000470中所探讨的那样。在高分子场的情况下，进动是超快的。封面图像显示了铁磁材料（蓝色球）的分子场（柔和箭头）中电子（灰色球）的自旋旋进（彩色箭头）。
