Abstract

Thermoelectric power (TEP) of two YBaCu07-8 compounds (with 6 =0.17 and 021) was measured as a function of quasi-hydrostatic pressure up to 9 GPa at 300K on samples with low porosity. In both cases TEP decreases with increasing pressure, at a rate -0-8uVK-'/GPa. The data obtained under hydrostatic pressure up lo 3CPa are in good agreement with those under quasi-hydrostatic pressure. The TEP of both compositions is found to decrease linearly at a rate 0.8 uVK-1GPa above 1.5 GPa.13;
