Preparation and Dielectric Properties of Cr Doped Multiferroic BiFeO3

摘要：

　　A series of Cr doped multiferroic BiFeO3 (BFO) with the composition of BiFe1-xCrxO3 have been prepared using hydrothermal method,in which x varies as 0,0.05,0.1,0.2,0.3,0.4 and 0.5.The synthesis temperature is carried out as low as 230 ℃ under hydrothermal conditions.With the increase of the content of Cr,the second phase is gradually increased.When the value of Cr is 0.5,the main peak (110) and (104) of BFO tends to disappear,in which the structure of BFO is changed.The permittivity of as-prepared samples decreases with the increase of Cr content and excellent frequency stability is exhibited.Better grain structure can be obtained for samples sintered at 830 ℃.
