| Abstract: | The dielectric loss during preparing processes of the SrFeCo0.5Oy prepared by the microwave heat was measured by rectangular cavity perturbation method. The dielectric losses was investigated under the condition of different temperature and different keeping time, the samples were characterized by XRD. The results show that the dielectric losses were influenced by the change of phase in the samples. The relationship among the phases in the samples prepared by microwave heate was also discussed. |
| Keywords: | microwave dielectric loss Rectangular cavity perturbation method SrFeCo0 5Oy phase structure phase content |
