The LaMnO 3.08 manganite system was studied as a function of temperature ranging from 10 up to 292 K using the perturbed angular correlation local probe technique at ISOLDE‐CERN facility. The electrical field gradient (EFG) measurements performed across the different temperatures revealed a single EFG distribution, corresponding to a unique probe local environment. In contrast with the small‐polaron picture, no fully Jahn–Teller distorted Mn 3+ O 6 octahedra was observed in this insulator sample. A local single‐phase scenario with uniform Mn charge distribution is proposed.
