Description

We present data from powder scans of the High Tsub(c) (approx. 40 K) superconductor Lasub(1.8)Srsub(0.2)CuO4 as a function of temperature from room temperature to 10 K. We observe a K2NiF4-type structure, with no evidence for a structural phase transition or anomalous changes in the lattice constants. For T > or approx. 190 K the values of the thermal expansion constants are not unusual for a metal oxide. (author)
