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 LaMnO 3 , where 3 d orbits 3 x 2 - r 2 and 3 y 2 - r 2 are suggested to align “antiferromagnetically” in the a - b plane. By a calculation on the basis of a single-ion model including the intraatomic 3 d -3 d and 3 d -2 p multipole interactions and a crystal field, we show that the basic multiplet structure of the LD spectrum… CONTINUE READING
