Abstract
We have carried out microwave measurements on an iron-rich Metglas at 9, 24, and 73 GHz. Two different techniques were used. FMR absorption measurements were made at 9, 24, and 73 GHz which allowed us to study the magnetic properties within a thin surface layer. FMAR transmission measurements at 73 GHz were also made which revealed some of the bulk properties of this material. It was found that the values of magnetic damping obtained from the FMR absorption measurements were significantly different from those obtained by FMAR transmission. We believe this difference is due to the insensitivity of the FMAR transmission measurements to microscopic inhomogeneities. The role of specimen treatment (annealing, polishing) was also investigated.
