Abstract
High-angle double-crystal X-ray diffractometry (HADOX) has been applied to examine the quality of La2-xSrxCuO4 crystals grown by the travelling-solvent floating-zone method. The two-dimensional intensity distribution in reciprocal space is measured for 0014 and 400 with CoK?1 radiation in a temperature range 60-260 K. The temperature dependence of the lattice constants is also measured. It is found that the crystal consists of grains or regions with different chemical compositions (?x?0.01), and that the corresponding crystallographic axes in different grains are parallel. A tetragonal-to-orthorhombic phase transition is reflected in changes in the crystal orientation, peak splittings and lattice constants as functions of temperature.
