Abstract
For samples of YBa2C4O7-delta obtained by sintering under high pressur e conditions (up to 3 GPa) by the use of solid-phase high pressure cha mbers (''toroid'' and ''lens''-types) and hydraulic press of 2000 tons forse the temperature dependence of the sag 1(T) within the temperatu re ranges of 78-1060 K was inverstigated. On the basis of the analysis of 1(T) relations shape-memory effect is determined and its feature a re studied
