From manganites to cuprates: a comparative study of the local lattice instability

Abstract:

Recent studies have shown that structural instabilities play a vital role in segregation of charge carriers in the perovskites. We have used extended x- ray absorption fine structure (EXAFS) to investigate the instability of the CuO6 octahedra of the Lai.85Sr0.i5CuO4 (LSCO) system showing high Tc superconductivity and the MnO6 octhahedra of the Lao.7sCao.25MnO3 (LCMO) system showing GMR (giant-magneto resistance) properties. Temperature dependent Cu K-edge EXAFS spectra on the LSCO and Mn Ked...
