Spin waves, which are collective periodic variations of the magnetization vector, have been found in both sodium and potassium. This is the first observation of genuine many‐body effects in a solid‐state plasma, and it confirms the collective Fermi‐liquid model first proposed by Lev Landau ten years ago.
