abstract |
The LaMnO3.08 manganite system was studied as a function of temperature ranging from 10 up to 292K 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 Mn3+O6 octahedra was observed in this insulator sample. A local single-phase scenario with uniform Mn charge distribution is proposed. (C) 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim |
