Description
The pair density function analysis of pulsed neutron diffraction data for the two-layer manganite La1.4Sr 1.6Mn2O7 indicates the presence of a large local Jahn-Teller (JT) distortion of comparable magnitude to that found in the perovskites, while the crystallographic structure shows a very small JT effect. A model that includes JT displacements provides a better representation of the local structure than the existing crystallographic one. While the local distortion is reduced at lower temperatures its change corresponds more to the increase in the transport in the ab plane than to the magnetic transition, reflecting the 2D nature of the crystal. copyright 1998 The American Physical Society
