We studied the magnetization (M) and electric polarization (P) in single crystals of BiFeO(3) with a unipolar ferroelectric domain in pulsed high magnetic fields up to 55 T. At low temperatures, the application of magnetic fields causes sharp changes in M and P at around 18 T, which can be ascribed to the magnetic transition from a cycloidal to a canted antiferromagnetic state. Measurements of P up to 600 K suggest that this transition disappears as the temperature approaches the Neel temperature. These results indicate that the field-induced change in P originates from the P component generated by the spiral magnetic ordering in BiFeO(3). Furthermore, we found that the microscopic magnetoelectric coupling constant of BiFeO(3) is greater than those of typical multiferroic materials such as TbMnO(3). This fact indicates strong coupling between the magnetic and dielectric properties of BiFeO(3).
