    Abstract

    Thermoelectric powers (TEP) of two YBa2Cu3O7-8 compounds13; (with 6 = 0.17 and 0.21) were measured as a function of quasi-hydrostatic pressure up to 9 GPa at 300K on samples13; with low porosity . In both cases TEP decreases with increasing pressure, at a rate - 0 .8pVK -1/(GPa). The data obtained under hydrostatic pressure up to 3 GPa are in good agreement with those under quasi-hydrostatic pressure . The TEP of both compositions is found to decrease linearly at a rate 0 .8iVK -1/(GPa) above 1.5 GPa .
