| Abstract | We report spectroscopic evidence for orbital-mediated phases in strained La0:5Sr0:5MnO3 thin films by combining soft X-ray spectroscopy and synthesis of manganite thin films. Measurements of polarization-dependent soft X-ray absorption reveal that electronic states responsible for the lowest-energy excitations in C-type antiferromagnetic La0:5Sr0:5MnO3 films have an orbital symmetry of 3z r, while those in A-type AFM films have an orbital symmetry of x y. Such orbital polarizations in strained films of manganite result from a combined effect of the Jahn–Teller distortion and the electron correlations of Mn 3d electrons. r 2006 Published by Elsevier B.V.
