Description
Single crystals superconducting La/sub 2-//sub x/Sr/sub x/CuO4 (x∼0.08)= have been investigated in the temperature range 15--298 K and are found to undergo a structural phase transition below room temperature, but above 180 K. Detailed analysis of the diffraction-peak profiles obtained below the transition temperature indicates a breakup of the macroscopic crystals into multiple domains of different orientations. Several cooling and warming cycles always reverse the samples into one-domain single crystals at room temperature. Complicated peak profiles prevent the determination of the exact symmetry and structure below the phase transition
