M. Ido et al., PRESSURE EFFECT ON SUPERCONDUCTIVITY AND STRUCTURAL PHASE-TRANSITION IN LA2-XSRXCUO4, Physica. B, Condensed matter, 194, 1994, pp. 2069-2070
The superconductivity of La2-xSrxCuO4 and the phase change from a tetr
agonal structure to an orthorhombic one are studied under high pressur
e The T(c) of the orthorhombic phase is depressed in comparison with t
he tetragonal phase. The depression of T(c) correlates with a change i
n transport properties between the Cu-O planes, which is caused by a t
ilt of the CuO6 octahedron.
