(a) Frequency-dependent magnetoelectric coupling coefficient α_ME measured in (1−x)BFO–xBTO ceramics with different compositions under a bias magnetic field of 6000 Oe, with inset displaying impedance spectrum and phase angle spectrum of the 0.75BFO–0.25BTO ceramics with x = 0.25. (b) Plots of magnetoelectric coefficient (α_ME) versus bias magnetic field H_bias for (1−x)BFO–xBTO ceramic samples with x = 0.25, 0.3, 0.35, and 0.4 (measured at 10 kHz).
