| 摘 要： | 研究约束在磁性薄膜畴壁中的自旋波Ｗｉｎｔｅｒ模式及其激励方式．用坡莫合金磁性栅格将高频均匀磁场转换成与自旋波Ｗｉｎｔｅｒ模式在时间频率和空间波长都匹配的磁场，从而实现相互间的有效耦合．采用锁相放大技术观测到了几百兆赫自旋波Ｗｉｎｔｅｒ模式微分吸收峰

| Abstract: | 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. |
