Ferrimagnetic materials were fabricated during the period for test and evaluation in each of the five frequency bands. Materials were prepared and evaluated in regard to their static and rf properties. The preparation and measured properties are discussed in detail in this report. In addition to material properties, measurement equipment being utilized on this program is described as well as new equipment being fabricated for bulk evaluation of circulator ferrimagnetic materials. Test structure design in three of the five bands 0.7-1.0 GHz, 5.4-5.9 GHz, and 8.2-12.4 GHz progressed at a satisfactory rate. Test results indicate that additional work is required to bring the structures within specifications at the band edges. However, it was established that performance is reproducible and symmetrical from port to port. In the other two bands 2.0-4.0 GHz and 4.4-5.0 GHz only minor refinements to existing structures will be required. Author
