Title: Infrared anisotropy of La/sub 1. 85/Sr/sub 0. 15/CuO/sub 4-//sub y/

Abstract

By calculating the infrared reflectance R(..omega..) for a collection of randomly oriented crystallites, we fit the reflectance of polycrystalline La/sub 1.85/Sr/sub 0.15/CuO/sub 4-//sub y/. From this calculation, the normal state of La/sub 1.85/Sr/sub 0.15/CuO/sub 4-//sub y/ is found to be metallic in the Cu-O planes and nonmetallic out-of-plane. The deconvolution of R(..omega..) into R/sub X/ and R/sub perpendicular/ allows the anisotropy of the system to be examined and provides a method by which infrared measurements of polycrystalline materials can be interpreted.
