A structure for short wavelength spin wave mode excitation is developed, which is used to investigate a spin wave (Winter mode) bound to the domain wall in a magnetic bubble film with an rf magnetic field produced by a microstrip carrying rf current, a thin permalloy grating on the top of the magnetic specimen generates secondary magnetic fields which match the time frequency and spatial wavelength of the spin wave, and an efficient coupling between them is realized By means of phase lock-in techniques a differential absorption peak corresponding to the Winter mode has been observed at 318 MHz.
