Multiferroic BiMnO{sub 3} with a highly distorted perovskite structure induced by the stereochemically active 6s{sup 2} electron lone pairs of Bi{sup 3+} was synthesized at a high pressure of 6 GPa. Magnetization, differential scanning calorimetry, dielectric permittivity, and in situ powder x-ray diffraction as a function of temperature were carried out, respectively. In light of comprehensive evaluation, we can conclude that the synthetic BiMnO{sub 3} ceramic displays ferromagnetic and ferroelectric orderings simultaneously, i.e., ferroelectromagnetism below its ferromagnetic Curie temperature T{sub M}{approx}100 K.
