Abstract

O K - and Mn L_2,3 -edges x-ray absorption spectra of orthorhombic TbMnO3 single crystals show strong polarization dependence, in contrast with results of previous experiments on orthorhombic LaMnO₃ and DyMnO₃ thin films that show nearly isotropic spectral structure. First-principles calculations reveal that TbMnO₃ exhibits a zigzag e_g orbital ordering ground state. The highly distorted MnO6 octahedron and orbital ordering in TbMnO₃ produce highly anisotropic Mn-O bonding within the ab plane, a frustration of the magnetic ordering, and the formation of complicated incommensurate magnetic structures.
