摘要：
This work reports multiferroic behaviour of bulk Bi2Fe4O9 exhibiting both weak ferromagnetic and ferroelectric behaviour at room temperature. Importantly the ferroelectric parameters and dielectric constant are observed to be sensitively dependent upon the magnetic field indicating the occurrence of spin charge coupling. Based on the dielectric measurements under the application of magnetic field, the magneto dielectric coupling (MD %) is found to vary from 0% to about -20% with increasing magnetic field. The observed variation in MD% is attributed to the weak magnetoelectric coupling in such systems.
