Stability of Jahn Teller distortion in LaMnO3 under pressure: An x-ray absorption study

Aline Y. Ramos, Hélio C. N. Tolentino, Narcizo M. Souza-Neto +3

The local environment of manganese atoms in LaMnO3 under pressure up to 15.3 GPa has been studied by x-ray absorption spectroscopy. For pressures below 8 GPa, no change is detected…

Hole-doping dependence of percolative phase separation in Pr_(0.5-delta)Ca_(0.2+delta)Sr_(0.3)MnO_(3) around half doping

Dario G. Niebieskikwiat, Rodolfo D. Sanchez, Liliana Morales +1

We address the problem of the percolative phase separation in polycrystalline samples of Pr $_{0.5 - δ}$ Ca $_{0.2 + δ}$ Sr $_{0.3}$ MnO $_{3}$ for $- 0.04 \leq δ \leq 0.04$ (hole doping $n$ betwe…
