抄録

Shock-loading experiments were done for as-prepared nonsuperconducting specimens of Tl2Ba2CuO6. The shocked specimens which were encased in the stainless-steel container with small holes exhibited a superconductivity of about Tc-75 K at 18 GPa, indicating that the overdoping state was released by oxygen loss during shock-loading. The x-ray powder diffraction pattern of the recovered specimens after shock-loading showed broadening of diffraction lines and a distortion to the orthorhombic symmetry. A transmission electron microscope image of the shocked specimen in which the orthorhombic distortion was observed in the x-ray powder diffraction patterns showed a twin structure.
