摘      要：In this work,we have presented a spin-coating method to produce thin films started with pure BiCrO3（BCO）and ended up with BiFeO3（BFO）by increasing x values in the（BiFeO3）x-（BiCrO3）1-x *** the produced thin films have been crystallized at the annealing temperatures of 400 ℃ for 0.5 *** XRD and EDAX spectrums give insight that the two crystal phases related to BCO and BFO stayed together within the thin film *** analysis showed that the prepared composite had macroporous morphology with interconnected pores and its width（size）decreased with increasing x *** strong correlations are observed among the microstructure,dielectric,ferroelectric,ferromagnetic properties and Fe *** all composites,the composition of 0.75 shows an attractive magnetization,polarization,switching and improved dielectric behaviors at room *** increase in the multiferroic characteristics of 0.75 composition is due to arise of lower leakage current by causing reduction in oxygen vacancy density,and enhancement of super-exchange magnetic interaction between Fe3＋ and Cr3＋ at BFO/BCO interface *** result shows that the thin layer on Pt（111）/Ti/SiO2/Si substrate possesses simultaneously improved ferroelectric and ferromagnetic properties which make an inaccessible potential application for nonvolatile ferroelectric memories.
