Reconfigurable short-wavelength spin waves. a Color-coded plot of transmission spectra S21 measured in the P state. The field is set to 3000 Oe first and then swept from 200 Oe to 0 with a field step of −2.5 Oe. c Color-coded transmission spectra S21 measured in the AP state. The field is set to −3000 Oe first and then swept from 0 to 200 Oe with a field step of 2.5 Oe. b Line spectra taken as cuts from the full spectra at an applied field of 100 Oe. These cuts are indicated by the dashed lines in a and c. d and e illustrate the excitation of n = 4 short-wavelength spin waves induced by the interlayer magnetic coupling in the P and AP configurations, respectively
