A solid solution between relaxor ferroelectric PbMg1/3Nb2/3O3 (PMN) and multiferroic BiFeO3 (BFO) has been synthesized by a solid-state chemical reaction route. The comprehensive x-ray diffraction studies of (1 − x)PbMg1/3Nb2/3O3–xBiFeO3 [(1 − x)PMN–xBFO] confirm the realization of stable and orthorhombic crystal systems. From the dielectric study, relaxor behavior has been observed, which is corroborated by a broadened peak and diffusive phase transition. The magnetoelectric (ME) properties have been explored through P–E loop, M–H loop, and magnetoelectric coefficient analyses. The simultaneous occurrence of polarization and magnetization reveals the ME coupling response of the PMN–BFO compounds. Excellent values of PS = 15.94 μc/cm2, Pr = 7.68 μc/cm2, MS = 12.96 emu/g, Mr = 1.25 emu/g, and ME coefficient value of 220 mV/cm Oe for x = 0.3 are obtained, which is helpful for magnetoelectric field sensor applications. To ascertain its sensing capability, a prototype has been developed, and the sensing behavior of the device has been established by placing it near a designed helical coil electromagnetic field generator structure.
