Abstract: Nano-barium ferrite for its outstanding performance in magnetism has been widely applied in areas such as micro wave-absorbing material etc.In recent years,the development and research on the wave-absorbing material have become a hot spot in the academic circles at home and abroad.In accordance with the requirements of the orthogonal experiment table,using the sol-gel method,we prepared the nano-doped W-barium ferrite.The samples were studied by TEM,XRD and VSM.Based on the experiment results,the best prepa...
