• Strong Linear Dichroism in Mn L2,3 Absorption Predicted for Orbital Ordering in LaMnO3.

抄録

The difference in Mn L_2,3 X-ray absorption spectrum between polarizations parallel and perpendicular to the c-axis, i.e., linear dichroism (LD), is discussed for LaMnO₃, where 3d orbits 3x²-r² and 3y²-r² are suggested to align ``antiferromagnetically'' in the a-b plane. By a calculation on the basis of a single-ion model including the intraatomic 3d-3d and 3d-2p multipole interactions and a crystal field, we show that the basic multiplet structure of the LD spectrum strongly reflects 3d orbital ordering and is insensitive to the Jahn-Teller distortion of the MnO₆ octahedra. LD is, therefore, shown to be a promising method to observe directly orbital ordering.
