What drives the charge/orbital ordering in La0.5Sr1.5MnO4: Jahn-Teller distortion versus orbital ordering

U. Staub, V. Scagnoli, A. M. Mulders +3

Temperature dependences of a magnetic and an orbital Bragg reflection at the Mn L2 and L3 edges of La0.5Sr1.5MnO4 have been collected. The temperature evolution of the orbital refl…
