Query: The Orbital Order Parameter in La0.95Sr0.05MnO3 probed by Electron Spin
  Resonance   The temperature dependence of the electron-spin resonance linewidth in
La0.95Sr0.05MnO3 has been determined and analyzed in the paramagnetic regime
across the orbital ordering transition. From the temperature dependence and the
anisotropy of linewidth and $g$-value the orbital order can be unambiguously
determined via the mixing angle of the wave functions of the $e_{\rm
g}$-doublet. The linewidth shows a similar evolution with temperature as
resonant x-ray scattering results.
