摘要：

An effective Hamiltonian scheme is developed to study finite-temperature properties of multiferroic BiFeO(3). This approach reproduces very well (i) the symmetry of the ground state, (ii) the Neel and Curie temperatures, and (iii) the intrinsic magnetoelectric coefficients (that are very weak). This scheme also predicts (a) an overlooked phase above T(C)similar or equal to 1100 K that is associated with antiferrodistortive motions, as consistent with our additional x-ray diffractions, (b) improperlike dielectric features above T(C), and (c) that the ferroelectric transition is of first order with no group-subgroup relation between the paraelectric and polar phases.
