Abstract

The local and average structure of the Ca endmember of the La_{1 - x} Ca_x MnO₃ series has been investigated. Neutron powder diffraction-based high real-space resolution atomic pair distribution function (PDF) analysis, yielding the local atomic structure, and the corresponding Rietveld analysis yielding the average crystal structure show that the two structural scales are in accord in this material, and that the MnO₆ octahedral units are regular for all temperatures studied. Quantitative values of structural parameters are reported for a wide temperature range, important for both experimental and theoretical considerations of hole and electron doped branches of the rich phase diagram of La_{1 - x} Ca_x MnO₃.
