Nature of Orbital Ordering in La_0.5Sr_1.5MnO_4 is Studied by Soft X-ray Linear Dichroism (2003)
Huang, D. J., Wu, W. B., Guo, G. Y., Lin, H-J, Hou, T. Y., Chang, C. F., ...
We found that the conventional model of orbital ordering of 3x^2-r^2/3y^2-r^2 type in the eg states of La_0.5Sr_1.5MnO_4 is incompatible with measurements of linear dichroism in the Mn 2p-edge x-ray...
