摘要：

A method is presented for performing Brillouin-light-scattering measurements on uniform-precession and low-wave-number (low-k) magnons excited by a microwave magnetic field in opaque magnetic specimens. The optical configuration is similar to that employed in conventional 180 degrees backscattering measurements, except that the incident and specularly reflected beams pass through the collection lens along different parallel paths. Examples of spectra from a Ni81Fe19 film are presented that include separate detection of light scattered from low-k magnons with the same frequency as the uniform precession.
