Single-phase magnetoelectric multiferroic materials with good coupling coefficients are very few and have wide applications. Numerous structural, optical, dielectric, and magnetic studies have been conducted in iron–vanadium-based double perovskites. With this, the current work focuses on magnetoelectric coupling of iron–vanadium-based double perovskite material Ba 2 FeVO 6 . The sample is prepared through conventional solid-state reaction route and X-ray diffraction confirms multiphase structure—orthorhombic structure (86.62%) with Bb21m space group and an R-centered trigonal structure (13.38%) with a space group of R-3m. Presence of Fe 2+ and Fe 3+ ions is inferred from X-ray photon spectroscopy analysis. Room-temperature ferromagnetism of the sample is detected from M–H loop and ferroelectric nature from P–E loop analysis. Temperature-dependent magnetization shows that material has a high Curie temperature of 745.9 K. Moreover, magnetoelectric coupling measurement shows that the material has the property of magnetoelectric multiferroicity. The observed coupling coefficient is 6.9 mVcm −1 Oe −1 .
