Evidence for the likely occurrence of magnetoferroelectricity in the simple perovskite, BiMnO3

Investigation of polycrystalline samples synthesized at high pressures as well as thin films deposited by nebulized spray pyrolysis suggest that BiMnO 3 is ferromagnetic with a T C of 105 K and ferroelectric with a Curie temperature of around 450 K. It remains ferroelectric down to low temperatures through the ferromagnetic transition.
