Abstract

The structural and magnetic behavior of the perovskite insulator La0.9Ca0.1MnO3 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 Tc (150 K), the behavior of the oxygen/manganese Debye-Waller factors is in clear contrast to its "colossal magnetoresistance" (CMR) counterpart La0.65Ca0.35MnO3. We speculate that the difference is intimately associated with the metal-insulator transition in the latter compound.
