| Abstract: | YBa2Fe3O8 (YBFO) is antiferromagnetic phase with triple-perovskite-structure,which plays an important role on our cognition about that structure by researching on its structural and magnetic properties.At present,studying about annealing temperature in using solid-state reaction technique to prepare for YBa2Fe3O8 are not enough,while controlling annealing temperature is one of importation steps in this technique.In order to obtain sample with high content of YBFO,the thesis adopts solid-state reaction techn... |
