We present results of an <i>ab initio</i> density-functional theory study of three bismuth-based multiferroics, BiFeO₃, Bi₂FeCrO₆, and BiCrO₃. We disuss differences in the crystal and electronic structure of the three systems and show that the application of the LDA+<i>U</i> method is essential to obtain realistic structural parameters for Bi₂FeCrO₆. We calculate the magnetic nearest-neighbor... Show more…
