The origin of the ferroelectricity in the indium‐based multiferroic perovskites (In 1− x M x )MO 3 (M=Mn 0.5 Fe 0.5 ), and the question of how to lower their magnetic ordering ( T N ) and the ferroelectric Curie temperatures, was investigated by density functional calculations. The analyses explain why T N is near room temperature and why the perovskites with s 0 and s 2 A‐site cations have similar ferroelectric distortions.
