Abstract :
The letter describes how the magnetostatic spectrum typical of an yttrium iron garnet film at microwave frequency can be partially suppressed or attenuated by means of absorbing layers still having the garnet structure. In particular, a triple-layered film is exploited in the parallel field configuration to eliminate all magnetostatic modes except the main one.
