Реферат:
Powder diffraction using synchrotron radiation and high-pressure cell has been performed for the HTSC compound Hg0.8Tl0.2Ba2Ca2Cu3O8.15 in the temperature range 100–300 K and external pressure 0–35 GPa. Observed structural anomalies at T2∼240 K and T1∼160 K have been attributed with stripe domain structure. A negative thermal expansion coefficient in a wide temperature range was observed at P=1 GPa. Analysis of crystal structure shows a suppression of T1 and T2 features by pressure. As external pressure leads to increase of Tc for investigated material, we suppose that superconductivity and stripe structure may have the same origin, but their interactions are competing. EXAFS (CuK-edge) measurements support this conclusion.
