Abstract

The structural and magnetic behavior of the perovskite insulator La_0.9Ca_0.1MnO₃ were studied as a function of temperature from 15 to 300 K by neutron powder diffraction. Although this compound shows an anomalous response of the lattice parameters around T_c (150 K), the behavior of the oxygen/manganese Debye-Waller factors is in clear contrast to its "colossal magnetoresistance" (CMR) counterpart La_0.65Ca_0.35MnO₃. We speculate that the difference is intimately associated with the metal-insulator transition in the latter compound.
