The pressure dependence of the structural phase transition (SPT) temperature in La2−x(Sr,Ba)xCuO4−y compounds is phenomenologically ascribed to the coupling between strain field and structural order parameter. The influence of partial substitutio

A single crystal of La 1.88 Sr 0.12 CuO 4 was studied by means of X-ray and neutron diffraction experiments and elastic measurements. The obtained data show that this compound undergoes a tetragonal to orthorhombic phase transition at around 260 K. T

Recent work has shown that the melt-powder-melt-grown (MPMG) high temperature superconductor YBa2Cu3O7 with Y2BaCuO5 inclusions sustains unusually high critical current in the bulk. In the present paper the magnetic irreversibility line of this mater

A Landau free energy suitable for describing the structural phase transitions in La 2−x (Sr,Ba) x CuO 4−y is derived by means of group theory. It is demonstrated that the coupling energy due to the interaction between stress field and structural

Measurements of elastic and structural properties of a single crystal La2-xSrxCuO4-y superconductor are presented. The longitudinal ultrasonic measurements were performed at 13MHz. A strong minimum in the sound velocity and a corresponding sharp peak
