Summary:•The solid phase method was used to synthesize BFO-xBYO with high crystallinity.•The magnetic properties of BFO-xBYO were improved.•The magneticdielectric effect become more pronounced in BFO-0.08BYO sample. Multiferroic materials BiFeO3-xBiYO3 (BFO-xBYO) (x = 0, 0.04, 0.06, 0.08 and 0.10) were synthesized by traditional solid phase method. Subsequently, the samples were tested for X-ray diffraction (XRD) techniques, magnetic field (M–H) hysteresis loops, field-emission scanning electron microscope (SEM), and magneticdielectric effect (MD). The magneticdielectric properties of such a composite were investigated versus room temperature, frequency (0.02 Hz to 2000 kHz) and magnetic field (1.4, 1.8 Tesla). The obtained values of the magnetodielectric (MD) for x = 0.08 ceramic sample was ideal, and the Mr = 0.1698 emu/g and Ms = 1.0541 emu/g were relatively higher, respectively. These results promise multiferroic BFO as potential candidate for manipulating magnetism through an electric field and provide great opportunities towards magnetoelectrically tunable multiferroic devices.
