Direct observation of orbital ordering in La${}_{0.5}$Sr${}_{1.5}$MnO${}_4$ using soft x-ray diffraction

S. B. Wilkins, P. D. Spencer, P. D. Hatton +4

We report the first direct resonant soft x-ray scattering observations of orbital ordering. We have studied the low temperature phase of La${}_{0.5}$Sr${}_{1.5}$MnO${}_4$, a compound tha…
