The Orbital Order Parameter in La0.95Sr0.05MnO3 probed by Electron Spin Resonance

Abstract

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 $e_{\mathrm{g}}$-doublet. The linewidth shows a similar evolution with temperature as resonant x-ray scattering results.
