Abstract
The microwave transmission characteristics of the ferromagnetic semiconductor CdCr2Se4 doped with Ag have been measured as function of the applied magnetic and electric field. The results are interpreted in terms of active helicon‐spin wave interactions; and the agreement between experiment and theory is found to be very good qualitatively. It is believed that the results presented in this Letter represent the first published evidence for active helicon‐spin wave interactions.Keywords
