La 0.9 Y 0.1 MnO 3 powders have been synthesized at different temperatures by the traditional solid state method. The crystal structures have been characterized by X-ray diffraction (XRD). The electromagnetic parameters were measured by vector network analyzer (VNA) within the frequency range of 8.2-12.4GHz. It , s found that the pure perovskite structure has been obtained at the temperature of 1250˚C. The bandwidth for R <-10dB became thinner with the sintering temperature , s increase from
