摘要：

The temperature dependence of the electron-spin resonance in La0.95Sr0.05MnO3 has been investigated 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(g) doublet. The linewidth shows a similar evolution with temperature as resonant x-ray scattering results.
