Figure 1: Schematic illustration of the mechanism for magnetodielectric coupling in partially antisite-disordered La2NiMnO6. Green: La; Blue: Ni; Red: Mn; Gray: Bridging O. The gray arrows on the O ions represent the magnetic interactions between neighboring magnetic ions. Charge transfer between the Ni2+ and Mn4+ produces a large dipole moment in the unit cell, which is suppressed by the ferromagnetic spin alignment in an applied magnetic field.
