摘要：

Investigation of polycrystalline samples synthesized at high pressures as well as thin films deposited by nebulized spray pyrolysis suggest that BiMnO3 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. (C) 2002 Elsevier Science Ltd. All rights reserved.
