Magnetoelectric multiferroics have received much attention in the past decade due to their
interesting physics and promising multifunctional performance. For practical applications,
simultaneous large ferroelectric polarization and strong magnetoelectric coupling are
preferred. However, these two properties have not been found to be compatible in the single‐
phase multiferroic materials discovered as yet. Here, it is shown that superior multiferroic
properties exist in the A‐site ordered perovskite BiMn3Cr4O12 synthesized under high …
