In this presentation, we report on the magnetoelectric properties of single-crystalline Ba₆Ln₂Fe₄O₁₅ (Ln = La, Pr, Nd), which exhibits spontaneous electric polarization and magnetic cluster formation by Fe³⁺spins. While a weak magnetocapacitance effect has been reported in polycrystalline samples of this system, the synthesis of single crystals has not been reported to date; consequently, the anisotropy and magnitude of the linear magnetoelectric tensor remain unclarified. We successfully synthesized single crystals of this system and elucidated their detailed magnetoelectric properties.
