Brillouin Light Scattering Study of Magnetic Excitations.

摘要

Of particular note are results on exchange in Li-Zn ferrite and surface magnons in thin films. Central to the research was the development of a high contrast, high resolution multipass tandem Fabry-Perot interferometer. The 4-plus-2 system has a contrast in excess of 10 to the 12th power and a background dark count below 1/3 count/second.
