| Abstract: | The microwave magnetic permeability (real part) of a series of demagnetized ferrites (pure YIG and YALIG) was measured in 3cm wave band,using the microwave cavity resonator method. The data were in close conformity with E. Schlomann's theoretical results. We also measured some characteristic parameters of the materials,particularly we made an attempt to determine the saturation magnetization and anisotropic onstant by using the law of approaching saturation and the computer fitting process. |
