BaFe_0.5Ta_0.5O₃ceramics has been successfully prepared by a solid state reaction method and structural analysis revealed that single perovskite phase was obtained in the ceramic sample. Room temperature magnetodielectric and magnetoimpedance properties of ceramics were investigated. Variations in the dielectric permittivity, loss tangent and impedance were evident. This confirms that a room temperature magnetoelectric effect can be obtained in BaFe_0.5Ta_0.5O₃ ceramics. Also, a higher grain boundary contribution than a grain contribution in the magnetoelectric effect was confirmed. The magnetoelectric voltage response as a function of H_bias suggested a room temperature nonlinear magnetoelectric coupling in BaFe_0.5Ta_0.5O₃ ceramic.
